Best of luck Waves. I took Chantix and it worked very well. Unfortuneatly, the failing of my last kidney transplant was more stress than I could bare. I fell off the wagon... hard. If you quit, stay quit! After nearly two years smoke free, it only took me about a week to get back to a pack a day.
Stay strong, I know I felt better, and had more energy when I wasn't smoking (cigarettes anyway). I was even able to climb up Medicine Bow Peak, 12,000 ft+, without much trouble. Although it's not a terribly difficult climb anyway, I don't think I could have done it had I been smoking at the time.
