Hi! I know this is crazy but I never drink water. To tell u the truth I might bring a glass every week....For months now I take tylenol (acetaminophen) everyday :/?

Drink more. You must be drinking some fluids as the kidney has obligatory urine production of at least 1 l/day. Trying to minimize fluid intake can't be a lot of fun and it can be potentially very dangerous. Tylenol (acetaminophen) is ok and long as dosing guidelines are not exceeded. Should certainly try to minimize that.
