How do you stop drinking soda?
Decide between quitting cold turkey and tapering down, clear soda out of your home, and plan for the first three days, when caffeine withdrawal peaks. Then ride out each craving for a minute instead of fighting it all day, and track every soda-free day so the progress is visible.
- 1
Pick your approach: cold turkey or taper
Quit completely, or cut back to a daily target over a few weeks. Tapering is gentler if you drink three or more a day.
- 2
Clear the easy yes
Move every can out of your fridge, desk and car. Most soda is drunk on autopilot, so remove the autopilot.
- 3
Plan for the first three days
Caffeine withdrawal usually starts 12 to 24 hours after your last drink and peaks around day two. Expect a headache, and keep water and sparkling water close.
- 4
Ride out each craving for 60 seconds
A craving feels permanent and isn't. Start a timer, drink something cold, and decide after it fades.

Watch the streak and the money stack up
A daily check-in turns quitting into something you can see: days, dollars and sugar cubes you didn't drink.
What happens when you stop drinking soda?
If your soda had caffeine, expect a headache and low energy starting 12 to 24 hours after your last can. Withdrawal usually peaks between hours 20 and 51 and is over within two to nine days. After that, energy steadies, cravings get quieter, and the money and sugar you skip start to add up.
- 1Hours 12–24
The first headache
If your soda had caffeine, withdrawal usually begins 12 to 24 hours after the last can. Headache and tiredness are the most common signs.

The hard part
Symptoms peak somewhere between hour 20 and hour 51. This is the stretch where most people give in, so it's where FizzFree's SOS button earns its place.

It lifts
For most people withdrawal is over within two to nine days. Energy steadies and sleep often improves.

The pull is weaker and passes faster. Triggers like stress or a takeaway meal are easier to spot, and FizzFree shows you yours.

What does the FizzFree app do?
FizzFree tracks your soda-free streak with one tap a day, counts the money, sugar and caffeine you skip, and gets you through cravings with a 60-second SOS. These are real screens from the app.
A streak you'll want to protect
One tap a day logs a clean day. Your streak, money saved and sugar skipped update instantly, and a free streak freeze each month means one bad Tuesday doesn't wipe out a good month.
Craving SOS for the hard minute
Tap SOS and a 60-second timer starts, along with a swap that actually helps and the reason you wrote down for quitting. Most cravings are gone before the circle closes.
Quit cold turkey, or taper down
Pick your approach at the start. Reduce mode tapers you from your current habit to a daily target over the weeks you choose, which takes the edge off the first-week headache.
Money, sugar and caffeine you didn't drink
Tell FizzFree what you drink and what it costs. It keeps a running total in your own currency, plus the sugar cubes and caffeine you've skipped, and a savings goal to spend it on.
Built for energy drinks and diet soda too
Choose regular soda, diet soda or energy drink. Diet drinkers track caffeine instead of an always-zero sugar number, and a weekly caffeine chart shows the habit falling away.
Find your danger hour
Log what set off each craving and what worked. Craving Insights maps them by day and time, so you can plan for Thursday afternoons instead of being ambushed by them.
The 30-day Soda Detox
One short lesson and one small task a day, from clearing the fridge on day one to handling weekends and travel. The first three days are free for everyone.
Should you quit soda cold turkey or cut back slowly?
Cold turkey is faster and works well if you drink one or two a day. If you drink three or more, or you've tried and quit within a week before, tapering over two to four weeks usually means milder headaches. Honestly, for heavy drinkers a taper beats raw willpower.
| Cold turkey | Taper (Reduce mode) | |
|---|---|---|
| Best for | 1–2 drinks a day | 3+ drinks a day |
| How long | Withdrawal over in 2–9 days | 2–4 weeks down to your target |
| Headaches | More likely, short-lived | Usually milder |
| What FizzFree tracks | Clean days and your streak | A fresh daily target, and on-target days |

What's the best app to quit soda?
Look for one built for soda specifically, not a generic habit counter. FizzFree tracks soda, diet soda and energy drinks, lets you quit cold turkey or taper, and shows the money, sugar and caffeine you skip. It's free on iPhone and Android, with no account needed.
How long does soda withdrawal last?
Caffeine withdrawal, the main cause of the headache, usually starts 12 to 24 hours after your last caffeinated soda, peaks between 20 and 51 hours, and lasts two to nine days, according to a Johns Hopkins review of 57 studies. Sugar cravings can linger a little longer.
Can I quit soda without headaches?
You can make them milder. Taper down over two to four weeks instead of stopping overnight, drink plenty of water, and keep sleep regular. FizzFree's Reduce mode builds that taper for you and sets a fresh daily target.
Does FizzFree work for diet soda and energy drinks?
Yes. Choose regular soda, diet soda or energy drink when you set up. Diet soda users track caffeine instead of an always-zero sugar figure, and energy drink users see both the sugar and the caffeine they skip.

No. There's no sign-up and no login. Your check-ins, streak and savings are stored on your phone, and you can back them up to a file yourself if you go Premium.
