I quite once and it was hard as hell. Aparently I forgot how hard it was cause I started up again about a year later. Now I smoke more than ever. It's a nasty habbit that's expensive as hell. I plan on quitting once I get my own place again. When i quit again, there's no way i'm letting myself start again. If I get stressed and feel the need, i'll punch myself in the nuts and realize that no matter how shitty the day is...it could be much worse.
