Hi, I use the topical wipes, Secure Wipes from pharmacy.ca. 2.5 mg strength.
I use them on my face, neck and on my shoulder length hair by parting it and getting it right on the scalp, about 1/2" apart.
It works really well on my scalp; well, most of the time, on my face and strangely my hands, which drip, are bone dry.
I also get the headaches, dry mouth and facial flushing. Lately I've been using Med e Tate, another wipe, at night and supplementing with the avert wipes.
The pills are hard for me because I have to eat frequently and the wipes bypass that aspect. This condition is so different for everyone that you just have to keep trying different things until you hit on the right formula for you. Good luck
