I have already quit going on 10 months ago. My date was June 9, 2005. I had just finally had enough and wanted to do this for myself, my husband and my 13 year old son. I can't say that it was really very much of a struggle for me because I wanted to do it. I picked a day and started my nicorette gum. I will never start back again. I smoked for 25 years. I do jazzercise three times a week and that I'm sure is the only thing thats kept me from getting fat. I have gained 9 lbs. I guess that has been the biggest struggle for me until now. Lately within the last couple of weeks now, I notice that there are time that I cannot seem to completely fill my lungs with air. Other times I can. I have not been coughing or spitting up anything. I'm making an appointment with the Dr on Monday to see about this. Its gotten to be real bothersome now. Has anyone else experienced this?
