Does caffeinated coffee effect you?

Hello kynni204 Sometimes if i put to much coffee i can't sleep at night, that's way i drink early in the morning and always put cream ot milk on it. One day, i made a black coffee in the evening, because i need to stay awake for study. I can't sleep until 3 o'clock in the morning and my exam is 7 o'clock in the morning, i felt sleepy but my eyes can't close until i drop my tear because i'm so sleepy. After that i'm afraid to drink black coffee in the evening. Good day

I dont drink it much but when I do get a chance it makes me sleepy instead of full of energy.That is really weird for me.My dad is the same way.I blame him.LOL

Unfortunatly caffine makes me sleepy, I know it's hard to believe but it does. I can't stay up with it, but it only happens with coffee.

Heck no, I could drink a pot of coffee and go right to sleep. I am probaly immune to it also. But oh well, I cant live without my coffee.
