The journey to change habits is difficult but worthwhile for long-term health**

One afternoon at the nutrition clinic, I met a woman in her 30s talking with the doctor. Ms. Lan — an office worker — had been drinking soda every day for 10 years. When the doctor informed her that she had fatty liver and prediabetes, she was astonished: “I only drink one can a day, not much at all, doctor.” But that small habit, repeated continuously, had silently eroded her health.

Ms. Lan's story is not unique. Many people know that soda is not good for them but cannot give it up, or think that “I can quit tomorrow.” In reality, quitting soda is much harder than many people think — because sugar is not only addictive but also closely tied to emotions, habits, and lifestyle.

In this article, we will embark on a scientific, gentle, and sustainable journey to gradually reduce and replace soda, suitable for all ages.

1. Why is it so hard to quit soda?

To reduce soda, one must first understand the reasons we cling to it.

1.1. Sugar causes physiological addiction

Sugar stimulates dopamine — the pleasure chemical in the brain. Each time you drink soda, the brain registers a “pleasant” signal, and the next time the body demands that feeling again. Therefore, many people feel restless and uncomfortable when they don’t drink it for a day.

1.2. Soda is tied to emotions

Many people drink when:

• stressed,

• bored,

• rewarding themselves,

• hanging out with friends.

Soda becomes a temporary “comforter.”

1.3. Soda is everywhere

• Eateries

• Grocery stores

• Convenience stores

• In the office fridge

When something unhealthy is too easily accessible, avoiding it is naturally difficult.

1.4. Family habits

Many people have been accustomed to drinking soda with meals since childhood. Growing up, that habit becomes even harder to break.

Recognizing the causes is the first step to starting change.

2. Change in 3 stages – the most scientific strategy to quit soda

You should not quit soda abruptly if you drink it daily. Gradually reducing it in stages is the method recommended by experts to avoid discomfort and excessive cravings.

Stage 1: from “every day” → “3 times/week”

2.1. Reduce frequency but don’t push yourself too hard

If you are drinking 1 can a day, set a goal:

• 3 times/week for the first 2 weeks.

This is a moderate reduction for the body to adapt.

2.2. Set specific times

Instead of drinking whenever you crave it → set specific drinking times, for example:

Only drink on Tuesday – Thursday – Saturday afternoons.

When there is a clear time frame, the brain will demand less “spontaneously.”

2.3. Avoid keeping soda in the fridge

Golden rule:

What is not nearby is less likely to be consumed.

Replace soda with:

• cold water

• unsweetened tea

• diluted lemon water

2.4. Dilute soda

A useful tip:

Mix half a can of soda + half a can of water.

It still has a sweet taste, but the sugar content is reduced by 50%.

2.5. Increase water intake throughout the day

Many people drink soda because… they are thirsty.

Drinking 1.5–2 liters of water/day helps significantly reduce sweet cravings.

Stage 2: from “3 times/week” → “1 time/week”

After 2–3 weeks, the taste buds have adapted. This is the time to reduce further.

3.1. Find “healthy sweet alternatives”

Instead of soda → try:

• unsweetened lotus tea

• water + apple slices

• sparkling water

• 100% juice with no added sugar (but don’t overdo it)

3.2. Train to drink lightly sweetened beverages

Reduce from strong sweetness → moderate sweetness → natural sweetness → no sweetness needed.

3.3. Observe your emotions

Ask yourself each time you want to drink:

• “Do I crave the drink or the feeling?”

• “Am I drinking because of friends or because I want to?”

Recognizing internal motivations helps us gain better control.

3.4. Keep a drinking diary

Record the number of times you drink/day, your feelings when drinking, and when you manage to resist.

Many people can quit just by… seeing the clear numbers.

Stage 3: from “1 time/week” → “1 time/month” or “no longer crave”

This is the maintenance stage — the most important one.

4.1. Define soda as “junk food,” not a beverage

A drink that is not nutritious cannot be considered something to drink every day.

4.2. Change rewards

When tired or wanting to “reward” yourself, choose:

• watching a movie

• taking a walk

• eating fruit

• drinking herbal tea

Avoid using soda as a mental reward.

4.3. Prepare favorite alternative drinks

• Lemon grass tea

• Diluted orange juice

• Brown rice tea

• Cucumber detox

When there are ready options, the brain demands less of what is unhealthy.

4.4. Focus on the health benefits achieved

• deeper sleep

• better skin

• smaller waist

• less fatigue

• better digestion

Seeing results helps us not revert to old habits.

3. The best drinks to replace soda

1. Water – the king of all beverages

Benefits:

• detoxification

• reducing appetite

• maintaining shape

• no calories

• good for kidneys, skin, and digestive system

If afraid of “bland,” you can add:

• lemon

• mint

• apple

• cucumber

2. Unsweetened tea

• green tea

• black tea

• artichoke tea

• chamomile tea

Contains antioxidants, reduces stress, easy to drink.

3. Naturally carbonated mineral water

Replace sugary soda but without sugar.

4. 100% pure juice (no added sugar)

Suitable types:

• orange

• grapefruit

• apple

• carrot

• watermelon

Should only drink 150–200ml/day.

5. Coconut water

Good for electrolytes, cardiovascular health, blood pressure.

6. Low-sugar smoothies

Such as:

• avocado smoothie + unsweetened milk

• banana smoothie

• mango smoothie

4. Tips to control soda cravings

1. Eat enough meals

When hungry → it’s easy to crave sweets.

Eating enough nutrients helps reduce the need for “quick energy.”

2. Chew sugar-free gum

Reduces the feeling of craving.

3. Rinse your mouth with mint water

The mint flavor makes the mouth “uncomfortable” with sweets.

4. Get enough rest

Lack of sleep increases cortisol → makes the body crave sugar.

5. Do light exercise

Walking for 10–15 minutes is enough to reduce cravings.

5. Mistakes that lead to failure in quitting soda

Many people are determined to quit soda for health reasons, but after a few days or weeks, they return to old habits. Quitting soda is not easy, as sugar is addictive and soda is tied to emotions and daily habits. However, what causes most people to fail is not “lack of willpower,” but because they inadvertently fall into the common mistakes below.

1. Quitting soda abruptly instead of gradually

This is the most common mistake.

People who drink soda every day often depend both physiologically (sugar stimulates dopamine) and psychologically. If cut abruptly, the body reacts with symptoms:

• headache

• restlessness

• strong cravings

• irritability

• fatigue

These reactions cause many people to “give up” after just a few days.

The correct way is to reduce gradually: from every day → 3 times/week → 1 time/week → 1 time/month.

2. Using diet soda as a complete replacement

Many people think that sugar-free soda will help them quit more easily. In reality, this is a psychological trap.

Diet soda does not contain sugar but contains artificial sweeteners, causing:

• taste disorders

• increased cravings for sweets

• gut microbiome disorders

• long-term risk of obesity and diabetes

Replacing regular soda with diet soda is just swapping one dependency for another, not truly quitting.

3. Replacing soda with drinks that are… even worse

Some people quit soda but switch to:

• bubble tea

• coffee with sweetened condensed milk

• canned fruit juice

• sweetened juice

• sweetened milk

The sugar content in these types can sometimes be higher than in soda.

Quitting soda this way is no different from “exchanging an old bottle for a new one.”

4. Not preparing alternative drinks

When cravings hit, if there are no other options, soda becomes the easiest choice.

Successful people often prepare in advance:

• cold water

• diluted lemon water

• unsweetened tea

• mineral water

• sugar-free fruit juice

Those who do not prepare will find it very difficult to overcome the “thirsty” moments.

5. Rewarding oneself with soda after… abstaining for a few days

Many people think they have abstained well, so they reward themselves with a can of soda. But this is exactly when all efforts go down the drain.

Sugar is addictive; just drinking it once, the feeling of “familiarity” immediately returns. The body will demand the old habit again, causing you to return to drinking daily in the following weeks.

6. Associating soda with emotional relief

If you drink soda when:

• stressed

• sad

• tired

• work pressure

• needing comfort

...then quitting soda will be difficult, as you have used it as a “mental medicine.”

Many people fail simply because they do not learn to relieve emotions through other methods, such as:

• taking a walk

• listening to music

• talking to friends

• drinking hot tea

If you do not replace emotional relief, quitting will be very fragile.

7. Not getting enough sleep – making the body crave sugar more

Lack of sleep increases cortisol hormone, making the body crave sugar for “quick energy.”

Many people think they are “addicted to soda,” but in fact, they are addicted to sugar due to lack of sleep.

8. Not observing progress and having no specific goals

Some people want to quit soda but do not define:

• goals

• reduction schedule

• allowed drinking frequency

• progress

They “try aimlessly,” and eventually give up.

Successful people often keep records or set clear goals, for example:

• this week ≤ 3 cans

• next week ≤ 1 can

• third week = 0 cans

Specific goals help the brain have a “point of reference.”

Quitting soda fails not because you are weak, but because you do not have the right strategy.

When you clearly understand the mistakes — quitting abruptly, using diet, replacing with other sweet things, not preparing alternatives, sleeping less, lacking goals… — you will easily adjust.

More importantly, remember that quitting soda is not about giving up a small pleasure, but about regaining a healthier, less sick, and lighter life every day.

If you want, I can write a shorter 300-word version, in checklist format, or a more memorable version for students.

Conclusion: Gradually reducing soda — a journey that requires perseverance but is worthwhile

Soda is not the enemy, but it should never appear every day.

Gradually reducing and replacing soda not only improves health but also changes lifestyle:

• a lighter body

• better mood

• better sleep

• reduced chronic diseases

• living healthier

Change starts from very small things:

a glass of water, a small decision, a day without soda.

And then you will realize:

A healthy body is the greatest gift you can give yourself.
