I used to drink enough to get a serious buzz around once a working week and I drink enough (although it's not always beer) to get full blown slammed at least once during the weekend.
I never drink alone though. I'll never crack a beer and just sit there and watch tv by myself or something like that. I need company.
The beer on weekdays got replaced with another intoxicant that doesn't give you a hangover though
Still don't do it alone though.
