I don't give a shit about text books pal. I lived in a house with 3-4 interchanging tweekers for 2 years. I know the ins and outs to a T. It's evil shit. Nice though that you haven't done it since.
I also have not smoked in a week Thanatos. It gets easier to quit every time you "quit" I guess. Atleast it seems for me. It's really just about desire and denying yourself. If you want to stop you will. With weed atleast.
I haven't smoked for about five weeks, and don't plan on doing it anymore. It's a time-consuming, money wasting habit. It gets easier every time I see others smoking and I just say no. Willpower ftw!
