When to Stop Drinking Lucozade Energy Original Before Bed
A 380 ml bottle of Lucozade Energy Original (46 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.
