I used to smoke. Gosh. I smoked for a Loooong time. I quit and was successful for 2 months and then St. Patty's day came... to much green beer and that was enough to get my smoking again. It was SO hard to re-quit but I managed. I do fear though one night out on the town again would damage my smoke free lifestyle. Fortunately I don't have to worry about that right now because I am pregnant. I'll cross that bridge well over a year from now....
