I started drinking beer before 18 and only drank half of it at the time. then kept only having beers avoiding other alcohols like vodka, whisky etc but then started to use them as well. but yet to date, I'm not addicted and things like "Yeah I should get a beer today" are not coming to my mind at all. I just drink only when it's available, I mean at parties, friend gatherings, birthday parties, etc.
