I haven't quit yet myself... but plan to one day. hehe. but go for it!! yay!

Oh, but i quess that really doesn't go with what you were asking...
My dad quit smoking about 2 years ago know... He had also went on diet.. and Kindof went to the extreme of what he was doing to himself..He went ALL THE WAY with getting healthy.. and lost weight.. he actually did. You don't have to believe it.. but it's the truth.. and I couldn't be happier for him. --- Still just going from what i've seen and heard not actually from personal experience.. maybe it varies???--- good luck still on it though if you do decide too.
