At 20 mg per 100 g, Milk Chocolate delivers about 21% of the caffeine in a typical 8 oz cup of brewed coffee (about 95 mg). For a wider comparison across drinks, try the caffeine comparison tool or browse the full caffeine database.

When to Stop Eating Milk Chocolate Before Bed

100 g of Milk Chocolate (20 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 Milk Chocolate sleep cutoff page has last-call times for four bedtimes, and the caffeine half-life calculator personalizes the curve to your metabolism.
