I usually only drink on Fri-Sat nights. Id say over the past year, Ive gotten lax on my intake and would have a beer or two every night during the week. Now I dont consider this wrong by any means, but as a health nut, it had to be stopped. When I say health nut, I go to the gym 4 days a week, run, and try and eat clean during the week (which also lapsed during the last year). Im not into the who eat organic, prevent cancer bull**** some are. I just like staying fit.
I now have reverted back to my old routine of clean eating during the week, except sat night. I dont drink beer but on Fri or Sat night. This is always a given unless I am on call. Usually its a decent amount too. Sometimes I will have a cocktail or two as well... If I have had a crappy day at work, I will have liquor instead of beer. Maybe some scotch or Irish whiskey on the rocks.
Honestly, I like to cut loose on the weekend and have fun when I can. Life is short. Enjoy it. If it becomes a problem, or looks like it might become one, then take care of it.
