Next week will be week 4 for me. I am out of the Chantex and thinking about filling another prescription. I have found this to be the hardest week so far and I am not sure why. I've got that tingling feeling this week that you mentioned and the last two days I really wanted a smoke but my willpower won out. Honestly I enjoyed smoking but I'm in my early 50's, I am divorced with an 8 year old that lives with me a bit more than half time, his mom was diagnosed with MS and has some real bad days, and he asked me to quit. I am doing it totally for him and my two older boys who had given up on me ever quitting. The request gets far more personal when you think of the possible future issues with his mother's MS and me smoking. There was no way I was going to roll that dice any longer.
