1) No, in fact I rarely drink as much as once a month anymore.
2) Not really. At university and high school there were a few occasions where I drank excessively to the point where I passed out or couldn't remember what I had done, but probably not more than I could count on one hand.
3) I really don't know about this. I'm not aware of anyone I know having a drinking problem so I don't really know anything directly about the impact it has.
TTFN,
