Quitting soda timeline: what the sources actually say
The only part of quitting soda with published timing is caffeine withdrawal. This page gives that window and what health sources say about sugary drinks, without inventing day-by-day milestones.
Not medical advice. QuitSoda is habit support for adults. If caffeine, sugar, pregnancy, medicines, or a health condition affect your plan, ask your clinician.
Short answer: If your soda had caffeine, NIH StatPearls says withdrawal can start within 12 to 24 hours, peak at 20 to 51 hours, and last 2 to 9 days. The CDC and ADA explain why fewer sugary drinks matter for calories and teeth, but do not give a day-by-day timeline.
The caffeine withdrawal timeline
Caffeine is the only part of quitting soda with a published timeline in the sources on this page. It applies only if your soda had caffeine.
- 12 to 24 hours after the last dose. Withdrawal symptoms can start, per the NIH StatPearls review (StatPearls).
- 20 to 51 hours. StatPearls gives this as the peak of withdrawal.
- 2 to 9 days. StatPearls gives this as the total length of withdrawal.
MedlinePlus says stopping caffeine suddenly may cause withdrawal symptoms such as drowsiness, headaches, irritability, and nausea and vomiting, and that reducing intake slowly helps prevent them (MedlinePlus). The FDA also advises cutting back gradually (FDA). If you want to plan around this, see cold turkey vs cutting back.
What the CDC and ADA say about sugary drinks (no timeline)
These sources describe what sugary drinks contain and why cutting back matters. They do not give a day-by-day schedule, so none is given here.
- Calories. The CDC says a 12 oz regular soda has about 150 calories from sugar, and that cutting out two regular sodas a day would reduce total calories by 2,100 in a week (CDC). QuitSoda doesn't promise weight loss. Calories from drinks may change depending on what you swap in.
- Teeth. The ADA says mouth bacteria feed on sugar and produce acids that can damage teeth, and that reducing how many sugary drinks you have and how often is a step in the right direction (ADA MouthHealthy).
- Replacements. The ADA lists water, unsweetened tea, and plain sparkling water among lower-sugar drink choices.
How to plan your first week
- Write down your three most common soda moments.
- Pick one unsweetened drink for each moment and buy it before day 1.
- Decide about caffeine: keep it in unsweetened coffee or tea for now, or cut back slowly as the FDA suggests.
- Remove the soda you keep at home or at your desk.
- Mark each day on the 30-day tracker.
- Plain sparkling water or seltzer, very cold, with a squeeze of fresh lemon or lime at home if you like.
- Unsweetened iced or hot tea, black or green.
- Unsweetened coffee, if the can was mostly about caffeine.
- Still water in a bottle you like, kept where the can used to sit.

Frequently asked questions
How long does it take to stop craving soda?
None of the health sources on this page give a timeline for soda cravings. For caffeine withdrawal, NIH StatPearls gives a total of 2 to 9 days. The ADA suggests replacing sugary drinks with healthier options, such as plain sparkling water or unsweetened tea.
What happens on day 1 without soda?
If your soda had caffeine, NIH StatPearls says caffeine withdrawal symptoms can start within 12 to 24 hours of the last dose. MedlinePlus lists drowsiness, headaches, irritability, and nausea and vomiting as possible withdrawal symptoms.
What happens after 1 week without soda?
NIH StatPearls says caffeine withdrawal lasts 2 to 9 days in total, so it can end before or after the one-week mark. The other sources on this page do not describe a one-week milestone.
What are the results of no soda for a month?
QuitSoda does not promise specific results, and none of the sources here describe a 30-day outcome. The CDC says cutting out two regular sodas a day would reduce total calories by 2,100 in a week. QuitSoda doesn't promise weight loss. Calories from drinks may change depending on what you swap in.
Is it easier to quit soda gradually?
The FDA says that if you want to cut back on caffeine, it is best to do so gradually. MedlinePlus says to reduce caffeine slowly to prevent withdrawal symptoms. The QuitSoda challenge lets you pick gradual reduction or a quit date in setup.
