Congrats on being a non-smoker. The MAIN reason why people gain weight after they quit smoking is metabolism. Now having said that, most people wont put on much more than 10 pounds due strickly to a metabolism change. I would say most people who gain substantial amounts are eating more than they did B 4 they quit. All of us are different. I had only put on 5 pounds in 2 months but now that I am off the patch Im a little nervous I may gain more.....Im hopeful that because I am very careful I shouldnt gain more but if I do there isnt a bunch I can do about it, just have to wait until my body start performing better. Keep up the good work !!! being a non-smoker is far more important than struggling a bit with your weight for a few months.
