Is it normal to get tired from drinking caffiene?

i know caffiene is supposed to give you energy but everytime i drink coke or something with caffiene i get really sleepy.. Ive heard this happens to people with adhd, is this true?

BTW: I dont think i have adhd but ive never been tested.

Is It Normal?

  • Maybe you have mono, or even AIDS. I'm being serious, get your blood checked at the hospital.

  • Yeah it's so normal. Many people get it even me! I'll have two bottles of mt. Dew and I will crash for like an hour!

  • It's normal for me and I wasn't sure if I was alone with that condition. If I drink coffee especially two cups I'm so sleepy I need a nap.
