I smoked for 17 years, I have been quit for almost 7 days now. I went and bought patches about 4 days before my quit date, I also decided to quit on a spur of the moment kind of thing. everytime I tried to set dates, I'd get close to them and chicken out. I have not gained any weight so far, but it is still early. I am trying not to eat excessively.
Today, I feel like hell myself.
Good luck!!
