I get the same problem and use arid extra dry deodorant on them. You have to put it on at night though after taking a shower or bath but it works pretty well for me. Powdered alum - or even the crystal rock type of alum. Check your local health food kind of place - or even on-line for a store near you - Good old fashioned home remedy! Do you have any other troubling symptoms with this? Have you had a good endocrine evaluation? Excessive sweating can be caused from too much, or too little of some important hormones. I would suggest seeing an Endocrinologist. You need your GH checked, along with IGF-1 and Cortisol. Good luck, I hope you find some answers.
