I am glad to read all these responses! I would sweat so much when I was drinking. It could be freezing cold, and I would still be on the couch sweating, and just explain it away as "I'm a sweating kind of guy"...no, you're a drunk.
My job requires me to do public speaking in front of hundreds of people, and I used to have to plan out what shirt (aka, black) I was going to wear to work, because I would always have huge sweat stains under my armpits.
It's certainly gone way down since I stopped. Not gone entirely, but I suppose there is still just natural body chemistry in play.
