Caffeine Withdrawal After Green tea

Green tea typically contains about 28mg of caffeine per 8oz cup. A common daily habit of 4 8oz cups adds up to roughly 112mg, a level where quitting abruptly can bring on recognizable withdrawal symptoms.

What to expect

  • - People who stop green tea often notice the first headache or fog within 12 to 24 hours.
  • - At roughly 112mg/day from green tea, low energy and irritability are common through days 1 to 3.
  • - With a moderate 112mg/day intake, cravings tend to appear around your usual green tea time.
  • - Sleep quality often improves after a few days, even if the first nights feel restless.

A taper plan starting point

  • - Step 1: cut green tea to about 60mg/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 green tea 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.
