When to Stop Drinking Arizona Green Tea Before Bed

A 16 oz serving of Arizona Green Tea (15 mg) stays under the 50 mg sleep-ready threshold from the first sip, so a normal serving is unlikely to delay sleep on its own. Multiple servings stack, though: caffeine's median half-life is about 5 hours, so a second or third serving in the afternoon can still add up past 50 mg by bedtime.

The Arizona Green Tea sleep cutoff page has last-call times for four bedtimes, and the caffeine half-life calculator personalizes the curve to your metabolism.
