Yes, and as most Uni students will tell you, probably too much, too often. I seem to lack the ability to become addicted to stuff though so I'm not worried. The only one usually worried is my wallet.
There's nothing like a fine stout with a couple mates in the pub, or a fine lager on a warm sunny day barbequeing, or a glass of wine to a fancy dinner, hell even the girly cocktails go down from time to time. There's a time and place for every drink.
