I Have OAB. I Started Taking Myrbetriq One Week Ago.

I have OAB. I started taking Myrbetriq one week ago. It hasn't helped yet. I was told it could take 2-4 weeks or more to work. The other option offered to me was BOTOX. Now I am reading about Electrical Stimulation for Overactive Bladder. In your opinion, which would be better to use if the Myrbetriq doesn't end up working? I want to avoid as many side effects as possible but it would be great to sleep more then 2 hours without getting up to uriniate. Myrbetriq doesn't seem to be constipating or give me dry mouth, which I wanted to avoid. Would love your opinion.
