Summer underarm sweating explosion... Is Botox for hyperhidrosis definitely effective?

Every summer, I am under so much stress because underarm sweat makes choosing clothes so restrictive and self-conscious. The clothes I absolutely never wear are those where sweat shows, like gray and pink. ..^^..

I've tried products like deodorants and Driclor, but my skin stung and itched so much that I couldn't use them for long. .

So, I am considering getting Botox for underarm hyperhidrosis. .

Does getting Botox really stop sweating? , I'm curious how many months the effects usually last. .

And is the pain severe during the procedure? , I would appreciate it if those with experience could let me know if it is possible to resume daily life immediately. .
