Im 19 turning 20 in 10 days :-D Been smoking up for about 11 months now, in those 11 i probaly missed a weeks total of the stuff. After smoking up about a week back i felt a burning sensation in the lower right part of my abdomen and it really freaked me out but i thought that its nothing major, after smoking up the next day it had the same effect even worse, i was too scared to fall asleep so i decided not to touch the stuff again. This is my 3rd day and im having stomach pains, no appetite,diarreah,headaches, a pain in my neck and sometimes back but at least i find life generally more interesting now :-D Good luck to everybody trying to quit out there :-))
