Hyperhidrosis, I'm sick of my underarm sweat

I'm trying to get rid of my underarm sweat. It doesn't matter if it's hot out, 20 degrees F, if I'm exercising or just laying down. I sweat a lot. I'm so sick of it. I don't have enough money for treatments like botox or MiraDry.

I was wondering if there are any chemicals I could put on my underarms and try to chemically burn that skin so I can no longer produce sweat in my underarms. Dangerous and stupid, yes, but I can't stand this sweat anymore.

What chemicals would you guys recommend?

If there's a better forum for this o be on, please let me know.
