Common questions
Does chamomile tea have caffeine?
No — chamomile tea is naturally caffeine-free: 0 mg in a typical cup. There is nothing to clear before bed, so no cutoff time exists — the half-life math has nothing to work on.
When should I stop drinking chamomile tea before bed?
Whenever you like, caffeine-wise. If a full bladder or heartburn wakes you, finish the cup an hour or two before lying down — that's a volume question, not a caffeine one.
Method
Cutoff = bedtime − T½ × log₂(dose ÷ limit). At dose = 0 the answer is "never stop" — which is why this page has one cell instead of nine. Every other drink in the library gets the computed table.
