Hey lads i had the same problem many years ago and it went away although not completely.
My hands and my feet used to sweat a lot. My close friends used to laugh at my hands-sweating cause it was so freak! I used to have my hands always wet. I even dropped sweat drops on the class table :? wich had 2 marks of humidity where i used to write :roll:
There is 2 things you must do to fix that problem:
1: stay easy, that means: relax, don't be anxious (yeah, i know... it's easier said than done and that's why we're all here for)
and 2: use some easy methods like odor stoppers, having always something to absorb sweeting (i used to have a pair of "cleenex" in my pockets so i could dry up my hands with them with no one taking notice of it)... you know... little tips to make your life a little better and so.
Nowadays i don't even care about it although i still have wet hands sometimes.
Feet are easier to treat. You can use thick cotton socks which will absorb great quantities of sweat. And one thing i believe that works very well is cleaning up your feet the best you can and then drying them COMPLETELY after each shower. It avoids bacteria to grow, which would make your sweat smell quite bad... you know.
