I used to hardly ever drink. I'm talking maybe a couple times a year, but now I tend to on most weekends. As bad as it sounds, sometimes I feel rather at home with a cigarette and a glass of porter. I figure if I don't drink or smoke at all during the week and do it one night on the weekends I'll be fine. I only drink beer or whiskey, and I never really go overboard with it. When I smoke I buy additive-free cigarettes. Probably not that much better, but whatever; they don't have rat poison in them.
Gotta live a balanced life. I don't want to blast myself with fitness to the extent that I will despise it when I'm older. I love being in shape and looking good, but I'm not super into the physical endurance stuff like running and all that. If I was, I probably wouldn't ever drink or smoke, but since I'm not, then I see no reason to hold myself back from doing it once a week.
