There seems to be a rash of people with the problem of excessively sweaty hands, or did I imagine reading such a thread just the other day.
Cant comment directly on just how bad your situation is without actually seeing it for myself, but the excessive sweating is known as hyperhidrosis. There are various remedies, and the one of the more memorable treatments is Iontophoresis, which involves water and electrical currents! ;)
