People notice when you quit

I've been using only for a little more than a year but I can surely say I've abused. I'm on medschool and since 1st semester (I'm on 3rd) I've been smoking daily on weekdays and weekends, I even got to the point of showing up high off of wax. I do make ocasional stops because I get tired of it, and I've noticed multiple times that when I do people start complimenting my appearance saying I look well rested, sharper and overall better looking. I don't know, this may help someone stay sober.
