Nobody liked a few beers more than I did but, when I was driving, it was strictly no booze for me.

I would guess then, BWM, that after 'a few beers' you did not drive until after, say, 2pm the following day? Refering to the chart in the link I gave earlier if your BAC was .24 - Three times the legal driving limit - it would be 15 hours before you had no alcohol in your body! No criticism intended if you did but the point is that the 'no booze' rule is not as easy as it sounds!

I don't have any answers either but surely a 'fit to drive' test would be a much fairer arbiter than simply measuring alcohol wouldn't it?
