Since the half-life of coffee is around 6 hours, that means if you have a coffee at 6pm, by midnight there would still be 50% of it in your body, and this caffeine has a direct impact on sleep quality.

由于咖啡的半衰期约为 6 小时，这意味着如果你在晚上 6 点喝咖啡，到午夜时体内仍会有 50% 的咖啡因，而这会直接影响睡眠质量。

Cocaethylene has similar actions to cocaine, but its half-life is longer, and it has an greater-than-additive effect, enhancing the body's responses to both alcohol and cocaine.
