Throughout the week I'll drink very little, usually just a couple if I drink at all. On weekends I'll have 4-6 each day. I usually don't drink until after my son goes to bed, but it still takes me hours to drink that much. I'm definitely slowing down as I get older.
the amount hasn't decreased much, but over the years, it has changed from ipa's to regular strength to, for the last couple of years, mostly milds. ramped the beers up recently because i'm supplying the beers for parties a lot recently
