Congrats on the 5 days. I have no ability to moderate many things. Smokeless tobacco was one of them. I was going through a tin a day, and wanted a chew in every waking minute. I needed to quit.
That said...for some reason I can moderate cigs. I don't have any now, but in the past could have a couple in a night, then go months or years and repeat. Then again, I never really was a smoker, so that might be why.
Anyway...not the point. Good luck.
