I just want to share a bit of inspiration. I write for a living, and my greatest fear about quitting was that I would never be able to write without a cigarette in my mouth. I suspect that other creative people may have this concern. But, now that I'm a seasoned Ex (joke--it's been about 75 days so far, though), I was surprised to discover that smoking had nothing to do with my creativity. If anything, it stalled me from getting on with my business.
If anyone out there has concerns about smoking stifling creativity, I'd advise them to put the idea out of their minds. But, it doesn't hurt to have plenty of replacement behaviors that don't interfere with the process. In addition to NRT (final phase now--6-8 hours apart!), I have a pouch of cinnamon toothpicks at my side. This seems to work without adding calories. Since I derive no financial benefit from this company, I can tell you to go to Flavored Toothpicks - Lemon, Mint, Cinnamon Toothpicks – FlavoredToothpicks.com. I believe that the cinnamon flavor works best for this purpose.
As you can see from this post, quitting has NOT affected my ability to write!
