I've heard that people like these things... but I haven't seen them at a store.
As far as the withdrawal symptoms go, there wasn't anything. I don't get how someone who really wants to quit can't. I don't even want to quit, and I've gone 2 weeks now.
Have you ever gone without chocolate for a week or so? - like that just a little harder. I'm not going to quit chocolate, and I'm pretty sure I'm taking up smoking again, but I'll try to cut it down to a pack a week or something.
