The cigarette companies are smart, you want just one but you have to buy 20 so youll naturally smoke all those then want just one more again.

Get back in the gym, when you are craving go lift weights- the endorphins release you get from it puts you in a great mood and is proven to be more stress relieving than nicotene.

If you really want to get off I recommend getting sick sometime, I havn't smoked for 3 weeks since I got a cough and cold that made it miserable to smoke (withdrawl is only 3 days)
