How many cups of coffee can we drink in a day?

What do you mean? How many can you survive? How many are unhealthy? How many keep you awake?

I drink one or two (on very special occasions three) cups of decaf.

I usually drink two per day; two pots.

It’s harmless. Right?

No it’s not harmless. It’s not particularly harmful, but it can definitely have bad effects. Like insomnia. Or digestive problems.

I’d take it on a symptom basis. If you’re developing things like insomnia, you’re drinking too much. As long as you’re feeling okay, you’re probably fine.

@heyimlyn Harmless? One year it is; the next year it’s not. The controversy has been going on forever.

Insomnia, jitters, and nervous energy are indications that your body is handling the caffeine poorly. I think 2–3 cups is considered ‘in moderation’.

Maybe that’s why I always have insomnia..No more coffee then?.

“For most healthy adults, moderate doses of caffeine — 200 to 300 milligrams (mg), or about two to four cups of brewed coffee a day — aren’t harmful.”
