I go to a 2 yr college to become a RN (Registered Nurse). I have smoked pot daily from Dec. 17th to jan 29th. Swim notices it affects his abilities to study, care about studying, and overall intelligence.... Swim plans to stop toking Today. In the past I was bitchy and pissed off for about a week. I am 19. What withdrawls have others had when trying to quit tokin'? How long did it last? Swim needs to do good this smester, swim fucked up big time last semester, and nursing classes are fuckin' tough! Anyhelp or insight would be greatly appreciated by me!!
