Alcohol is a great anxiety reliever in the SHORT TERM, but in the long term it certainly exacerbates it.
With regards to sweating: although this is an obvious symptom of anxiety and panic, I noticed I sweated a great deal more when I was drinking. Especially if you are a heavy beer drinker, I think your body attempts to sweat out the excess liquid to an extent. Pretty much completely went away when I stopped drinking like that.
