LOL you're all crazy, one or two small drinks a day prevents heart disease and other problems. One a week will hardly put you out. I'm making great gains and I drink a bit more than 2 on some weekends. You'll be perfectly fine, never deprive yourself of the joys in life, you'll only burn out all too quickly.
Just think tho, Arnold drank a lot of beer almost every day, he may be a genetic freak but he's not THAT different, he's still human.
Try to avoid cokes whenever possible, but if you want a coke just remember to drink a good 128 oz of water a day and you'll be fine there too.
