For the past 13 years I've smoked about 2-3 packs a day. Last Friday(Feb 26) I smoked my last cigarette. To be honest, I haven't really been irritable til yesterday. According to those around me I'm easier to get along with but its hard. Very hard. The cravings are horrible. I'm going to stick with it, but I'm really beginning to feel the struggle. Anyone have any tips? I'd really appreciate it.
