Keep it up! I'm also quitting today. I just finished my last final of this semester, so it should be easier now.
I've smoked for almost 10 years, quitting a few times for varying amounts of time, the longest being 6 months about 6 years ago. I also quit back in September, but that only lasted about 3 1/2 months. I have no withdrawal symptoms when I quit, but I like the act of smoking. Cigarettes taste like crap and feel like crap, but I'm so used to doing it that I still have cravings.
The problem is that pretty much everyone I know smokes (including my girfriend, who doesn't want to quit right now), so it's really easy to fall back into it. Anyway, good luck. Your post inspired me to do it today instead of waiting (again).
