No

I always get tired when i drink caffeine, not an hour or a few hours later, just right when i drink it i never get the rush of it. Similarly alcohol doesnt make me drowsy in the slightest, it makes me more awake. ill still get drunk but i wont feel tired at all and i can never get to sleep if i drink. i dont take any prescription meds (my friend thought thats what would cause it) does anyone know what the issue could be?
