As a VERY rough rule of thumb, the body processes one unit of alcohol every hour. So take an average
Sunday session:
Curry lunch at the Mess, arrive at 12.00, 4 pints, feeling bit full, switch to wine, 4 glasses, back to my place, feeling better now, 4 more pints, call out for a pizza, 2 glasses of wine, one for the road? Alright, just a double Remy if you insist.
Total intake: 24 units. 12 units processed during the day, so you stagger of to bed at midnight with 12 units in your blood.
First wave? Met brief at 08.00? 4 units left, so that is the equivalent of 2 double vodkas for breakfast. Yum!
On the programme for a midday take-off? Blood alcohol effectively zero (unless you had 2 double vodkas for breakfast!)
Summary: It needs to be a BLOODY good session before the 12 hour rule is inappropriate.
