I can still fall asleep after having a large cup of coffee

Same here, coffee doesn't work for me in keeping awake as well. Sigh...

 

i don't drink coffee ..only tea and it too has the same opposite effect on me .. lol

 

I can fall asleep after drinking coffee, but not after drinking some sort of cola.

 

that maybe due to the fact that you are immune to caffeine (drink so much coffee that it now no longer works)...this happens to me too

 

I don't drink coffe. Don't like it. But if I drink tea before sleeping, i won't fall in sleep.

 

Me too! i dislike it whenever i wanna study but i still feel sooo sleepy and i could fall asleep easily even after a few cups of black coffee. my parents told me to try chinese tea though i don't really fancy tea.

 

Coffee doesn't work for me at all. I had a double espresso and went home afterwards and had no trouble sleeping. But if I'm trying to stay awake I used instant hot chocolate made with hot water. It works like a charm to keep me up.
