i know exactly how you feel man, sometimes i will chug some cool liquids down even if im not thirsty (or even really too fucking full to be drinking anything) just for the feeling of it going down my throat lol. gatorade is my fav for this, i can pull those so quickly.

i think what you're describing is pretty normal though. i mean i don't drink quite as much as you but it doesnt seem unhealthy or too crazy to me, you just like to drink!
