Hi Ada,
Sweating is controlled by the sympathetic nervous system, in fact there is an operation available for hyperhiridosis where the sympathetic nerve is cut ,this proves to be a godsend for these people whose lives are often made so difficult from constant streaming from hands and feet.
I had very heavy sweating in the early days of my RSD but these days I am more like a prune

Of course there are other reasons we sweat and women going through menopause may also often experience uncontrolled sweating so if sweating is a problem and you are a women of 'the right age' then there maybe a non RSD element to your sweating and therefore some fairly routine treatment for it.
WE have a wonderful deodorant here called Driclor which only needs applying every 3 days, this helps and of course keeping away from synthetic materials by wearing cottons and wools will also help.
Apart from that I am not sure what other ways are best to manage it but it sure is a nuisance.
Regards
Tayla
