is that on an average night? or are meaning that I should take the total number of beers in a given time frame and then divide said number of beers by number of days in the afore mentioned time frame? Could be a big difference as some days/weeks/months/years I tend to drink more than average. Also, at what time do you consider "night" as starting? because on some days I tend to start fairly early. If I don't have to count those early beers, my numbers could decrease drastically.
