Glad to help:
I am not sure how many units, i think 50 per hand. That may be way off im not sure. I know I had around 50 injection sites per hand. Most on my fingers and on the side of my hand where you put your hand down to write.
No numbing agent. I have a fairly high pain tolerance and the pain of the procedure was not pleasant but do-able. I gripped bags of ice beforehand for about 10 min to numb my hands. It worked fairly well. An idea of mine for next time i have it done (i think i will have it done around every 5 months) is to wear a waterproof glove and emerse my hands in ice water.
The area around the injection sites stopped the sweat completely. I am very happy with it. I still used drysol (aluminum chloride) about 2-3 times a week to clear up the areas in between. But i dont pour sweat out of my fingertips or side of my palm and that is a huge blessing.
I had it done at my local dermatologist in Roanoke VA. Any dermatologist can do it. Since I had tried drysol and iontophoresis (both with inadequate results, but i admittedly was doing it wrong) I got the injections approved through my insurance. It took about 4 months to get the approval. I pay 200 dollars each time i have it done instead of the 2000 i would of had to pay.
I use 14 mAs on my feet every 3 to 4 days. I do 15 on each polarity for a total of 30 mins. That is my maintenance schedule. Sometimes i can go longer without doing a treatment it just depends. Normally it is 4 days. I get about 90-95% dry when i do the treatments on time.
Before I had been doing it with 20 mAs and was getting poor results, if anything i was sweating more. So i stopped for two weeks and then started on a different regimen with the 14 mAs, 30 min a day, for 10 days in a row and that worked for me.
Whenever i add baking soda to the trays it seems like i sweat more in between treatments. Other people have commented the same thing, maybe its in my head but i really do think it actually hinders the effect of the treatment.
If you are still having trouble try getting sweat-stop instant:

it is rather expensive but it REALLY works when you need to not sweat at all. If my botox is wearing off, as it does after 2-3 months, i use this on my fingertips and it stops the sweat completely. I feels a little uncomforatble though. It feels like your hands are dirty, at least thats the feeling that i get. I only use it if i am going into a meeting or an interview or something like that.
Hope this helps! best of luck
