I feel pretty darn good (day 50 was admittedly pretty exciting, thanks for the acknowledgement Timbo!) I still want to smoke at times, maybe 2-3x per day on average. But like I said downthread, I've also had a couple days now when I didn't think of smoking at all, which has been pretty sweet. I do not feel that I've got another quit in me, and that is motivating me to not bail on this one, for any reason. My brain keeps casually suggesting that "just one" would be nice and no big deal - this is the one and only remaining "argument" I'm experiencing at this point, everything else has been weeded out and pruned away. ... To which I say, "Haha, nice try, lower brain! I'm on to your shenanigans and I'm getting on with my life now."
