Is there a product to stop my hands from sweating too much?

I naturally have clammy hands. It's embarassing to shake people's hands. Especially if it's for an important job interview. I wipe my hands before I shake with someone but it's still clammy. I can't even drink coffee or it's a puddle in my hands. When my boyfriend notices that my hands are dry they start to sweat on command. What is a clammy handed girl to do?

Is there a product to stop my hands from sweating too much?
I think that that is a health condition ... cant remember what its called but I think that Your doctor can help. Its a sweat gland that is hyperactive . Some people have this with their feet ,, and doctors have told them to put anti persperant on their feet to help... I dont think you would put secret on your hands... You might have to take some medice or go to a Organic Grocery and see if there is a product you can use... Mabey there is some sorta medicated hand lotion you can use to stop the sweating ...
