For those who use drysol to stop excessive sweating, how much do you put on at night?

I got the bottle with the dab o matic applicator and i have been putting on a dab to cover my entire armpit area(7 - 8 dabs) but it has been burning so much that I cannot sleep, although less now than when I first started putting it on. I also notice that it drips down to other parts of my armpit that I did not cover. Do you think this is too much? How much do you put on yourself?
