☕ Is It Weird to Drink Coffee After 8pm?

Short answer: unusual, but some people handle it fine.

It's not weird, but it might affect your sleep depending on your caffeine sensitivity.

Caffeine has a half-life of about 5-6 hours. So if you drink coffee at 8pm, half the caffeine is still in your system at 1-2am. For most people, that's going to mess with sleep quality even if you can fall asleep.

However, regular coffee drinkers develop some tolerance. Some people can genuinely drink espresso at 10pm and sleep like a baby. Genetics play a role — the CYP1A2 gene determines how quickly you metabolise caffeine.

If it doesn't affect your sleep, crack on. If you're lying awake at 3am wondering why you can't sleep, you might have your answer.
