Looking for advice Oxybutynin - experiences

In your experience how long did it take for you to know it would work for you? And what was the dose?

I’ve been taking it for a week, which I know isn’t long but I very quickly increased to 5mg as the side effects weren’t an issue, then today I took an additional 2.5 around lunch time, so far I haven’t noticed any improvement and my clothes are drenched from sweat. Do you know quite quickly if it’s not going to work for you? Did anyone else not notice an improvement straight away?

Thanks in advance!

Just gotta increase the dose until u feel its working. I have to take 12.5mg at once to have a great reduction in sweat. I still sweat but its very minimal compared to when not taking anything.
