I did it cold turkey back in Dec 03. I say, Just Do It. It's uncomfortable for about the first 3 days- then after that, it's just a psychological need that you'll need to use discipline to overcome.
You can do it! The rewards far outweigh the short-lived gratification of a smoke.
The longer you go without, the better you feel each day. And to conquer the addiction is the best feeling in the world.
ETA: I realize you've been doing it cold turkey for a month now-- my comments are just general for anyone trying to quit smoking.
I was a heavy smoker for many years and decided to go cold turkey. It is easier to quit while not being in your normal routine. I did it during a 15 day trip, and it worked.
I have to ad that I was not "trying to give up". I decided I was stopping, bit my tongue and prepared myself for the cravings. That's what worked for me. One of the best decisions I ever made in my life. It's around a year now and I finally don't crave them at all.
