When I go a few days w/o smoking, I definately notice an increase in how fast I get pissed off. The first day or 2 of not smoking isnt that bad to me because once you have smoked for a month or more everyday, sobriety is kinda fun for a while.

All hell breaks loose on the third day though. The last 3 or 4 breaks I have taken have always been the worst on the 3rd day. I just snap on people at work, at my house, and freinds. It dosent help any that I have had a VERY bad temper for the majority of my life either.
