When to Stop Drinking Lipton Iced Tea (bottled) Before Bed
A 20 oz bottle of Lipton Iced Tea (bottled) (25 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.
