I used to be a big drinker as a student but I don't think I am any more. But a friend has said that the amount I drink is verging on a problem. I usually have one or two glasses of wine in the evenings. Once a month or so I might have 4, which is my limit before I get drunk enough that my words become slurred. If I'm out with friends I might have two vodkas.
I never drink to get drunk, just to enjoy the drink, and never drink and drive. So I think I'm a responsible drinker.
