I don't drive when I drink, but I found myself 'not driving' an awful lot. About four years ago I was at a routine doctor's appointment which happened to be the Monday after an all weekend golf tournament/drinking binge. My BP was 230/110 and I was a few shades of unhuman color. I was told to go see my GP (this was a foot doctor), and was told that if I continued down this path, I would not live to see my daughter graduate high school. I stopped drinking for 8 months and got back on the bike - the rest is history.
I got back on the bike because of alcohol, but not because the law told me to. I now moderate my drinking and am able to enjoy a cocktail here and there while still being able to ride whenever I want to.
