The good thing is you want to quit smoking. I suggest reading this book. Best $15 I've ever spent. I read the last page and never lit another cigarette again. Never even had the urge. I honestly couldn't believe it. You can smoke your brains out during it. It even says so. I'm not saying it's going to work but for the $$ why not try.
