It's that true that drinking a coffe make someone can't sleep at night?

I can drink coffee day and night and right up to the time I lay down to sleep. I never have trouble sleeping. I think most people have trouble sleeping if they drink it at night. Not me though.

I like to drink coffee during the day, when I work when I'm sleepy, but it doesn't make it difficult to sleep at night, even when I drink coffee I like to be sleepy

If I drink coffee in the evening I have no problem falling asleep. But I've noticed that sometimes after I drink coffee in the morning I start to yawn. Maybe it has nothing to do with coffee but is because of what I ate.

Not entirely true. It depends on the person. My husband drinks coffee at 11pm and still snoring in bed. LOL

if i were to answer your questions, based on studies and of course coffee has caffiene which stimulates the nervouse system, That will make you awake! I always drink coffee at night for me to stay awake specially when i have so works to finish that night!

I drink a lot of coffee but it seems to vary, if I have a light brew which seems to be a normal cup for many people- I can often sleep in spite of it, but too close to bed time and it will keep me up. I enjoy a good strong espresso black coffee of the Starbucks or Cafe Bustella variety. My treat coffee is a nice iced coffee or hot latte which I add vanilla almond milk to. Oh my, I may not sleep tonight I can just smell the coffee brewing now :)

Different people have different effect on them. I drink coffee and still sleep well afterwards.

It's more like coffee force you to keep awake whether it's at night or not. It's caused by caffeine and there's scientific explanation on how caffeine works. I'll leave the youtube link here Personally. I don't think caffeine or coffee has that much affect on my sleep activity or maybe because i don't drink coffee that much.
