I used to sweat excessively for many years. Didn't matter whether I was nervous or not my shirt used to be wet from my underarms all the way down, it was so embarrassing. Didn't matter what I tried to do, even used deodarants which said that it will keep you dry longer, they never worked. I have since found out that it is one of the symptons of SA. I don't know how but the problem has now gone and I am so much happier and don't feel so self conscious.
