I've made the mistake of drinking what I would consider a reasonable and safe amount under normal circumstances, only a few hours after a big workout. It messed me up big-time. Multiplied all of the bad effects from alcohol.
I rarely drink these days. Its a bit pointless. I do enjoy a nice beer or two with dinner when I'm away on holidays, and have the occasional party (maybe twice a year) with friends where I have a few more - but nothing close to being drunk. All in all, I'm not much of a big drinker. When I turned 18 I had way too many big nights getting drunk, and I'm glad it was a phase that passed very quickly.
