What to do about sweaty hands?

[Pascal]

My hands sweat way to much when i practice piano by
myself or with others, even more when i perform.

I've tried baby powder, i've tried flower -> my hands
would just get all muddy with all the sweat.

I've tried  medicine my doctor
gave recommended: xerac but it didnt work well.

so far i keep a towel handy.  but its still a problem.

What usually works for me for a performance is to keep a napkin or paper towel in my pocket for an easy dry.  Besides that, I don't have many suggestions.
