Caffeine Withdrawal After Coca-Cola
Coca-Cola typically contains about 34mg of caffeine per 12oz can. A common daily habit of 3 12oz cans adds up to roughly 102mg, a level where quitting abruptly can bring on recognizable withdrawal symptoms.
What to expect
- - People who stop Coca-Cola often notice the first headache or fog within 12 to 24 hours.
- - At roughly 102mg/day from Coca-Cola, low energy and irritability are common through days 1 to 3.
- - With a moderate 102mg/day intake, cravings tend to appear around your usual Coca-Cola time.
- - Sleep quality often improves after a few days, even if the first nights feel restless.
A taper plan starting point
- - Step 1: cut Coca-Cola to about 50mg/day for a week (smaller or fewer servings).
- - Step 2: drop to about 30mg/day for another week.
- - Step 3: reach 0mg, or hold a small amount if that feels more sustainable.
- - Replace Coca-Cola breaks with water, a short walk, or a 20-minute nap to ride out dips.
- - Keep steady sleep and meal times; that alone eases many withdrawal days.
