yes.. eventually you'll be able to breathe like "normal" your lung capacity may be slightly deminished, but it won't be that bad.... not after 3 years. as for the appetite, i've never had a problem with that. i chew nicorette, so that gives me something to do... i think thats what the whole "appetite" thing is, you just need something to do, buy a pack of gum or something... or just control yourself = P
