How can I stop sweating so much under my arms while I am on my adderall?

I am on adderall xr 30 mgs. One of the side effects of adderall is a lot of sweating. No matter what kind of deoderant I use, I still seem to sweat from my arm pits like crazy. It is very embarring in social gatherings and not to mention it's very uncomfertable. Does any one else have this problem and if so, what do you do to stop the arm pit sweat?
