alcohol and performance

Here's a story:I am not a drinker, I go out sometimes, but all I manage is like, a beer or two, pretty much i do that to socialize...Anyways, last time I went out "hard" was months ago and last nigit I just decided to let loose a bit and have some fun with my friends.Well, I did not restrict myself on the booze, so I ended up getting really drunk.Today I had a bad hangover and all those things related to a fun drinking night like that... I wanted to get myself in order and decided to still swim today(I just got back from practice and actually feel like new:))).So I was doing my regular stuff and then decided to time my 50 meter breaststroke to see how much I would suck because of the alcohol the night before.Well, off I go... hit the wall, stop the clock and guess what - personal best, and not just slightly improved, but by 3 seconds!!!I was shocked.I hope it was not related to my night of drinking, because I was swimming very hard and did not time myself in *** for 3 weeks, but still ... that's 3 weeks and 3 seconds.Oh maybe my day off from swimming yeasterday worked as a little taper,lol(I hardly skip a day of swimming, I have very few days off) and my muscles were rested or something - but hey, I was hung over. Just weird!!! What do you think?
