Not very night, occasionally not even every week. But when they start they can't stop.
Maybe every Friday and/or Sunday, 20 to 30 units each. Football home matches twice a month, full days drinking say 30 units. Sometimes more, enough to be sick.
Boys trip, maybe 3 times a year, 100 units total.
Holidays, 4 or 5 days out of 7 , 20 to 30 units a day.
If someone drank like this could they live a long life without major health problems?
