We have an excellent bunch of local breweries so I enjoy a craft beer a couplafew times a week. The darker stuff like stouts, porters and Scottish ales suit my slow sipping tendency. It can take me a couple of hours to finish a beer. Unless I'm eating pizza, bbq or Mexican food, in which case I'll wash it down with any old thing.
Like AlmostTrick mentioned it affects my sleep. Actually that's an understatement. Alcohol revs me up exactly like caffeine, so I try to avoid drinking too late in the day.
I have noticed a bit of a persistent pudge, although my weight is otherwise close to my peak physical condition weight of my 20s. I'm gonna blame the cream and sugar in my coffee for that.
