I'll be smoke free 5 years in January. I used the patch. If you use it, make sure you do the whole program. It's easy to think "this is easy" and go off it after the first stage. If you really want to quit cold turkey, try sunflower seeds and drink lots of water like RD suggested. Also, don't tempt yourself by doing things that you associate with smoking. To stop drinking coffee and stop smoking at the same time is a hard one though. But most of all, WILLPOWER!
