Hi,I am a 34 year old female,I have been smoking for seven years.I have just now decided to quit.I have taken up walking,i walk two miles a day,but my lungs feel like they can explode when I am done walking.Right now I am chewing a piece of gum,sour apple bubble gum,to be exact.Do any of the over the counter medicines help you fight the cravings,or help ease the nicotine fits,and all so the moodiness.I know this is going to be hard,but if I want to lose weight and feel better about my self,I need to quit smoking.What have some of you done,to quit smoking and what helped you.How long will it take for the nicotine to get out of my system?I have a husband and 3 children,I don't want to turn into a B-I-T-C-H,but I know I will,and I hate puttiong my children and husband through that.Any info would be greatfull and very much appreciated.
