Re: Another thing you forgot
Indeed. Assuming testing first thing in the morning (before you drive your train/bus/lorry into people), you will merely ensure not being too tipsy for these activities at that time.
Which leads to inevitable lunchtime drinks, and afternoon drinks, and then getting home and not drinking, because you've got to get your liver to process six pints in the next twelve hours.
This is actually a far better way to do drinking than the British 'neck a load in the evening until 1am' methodology, that guarantees a nasty hangover the next day.
