Mirabegron
"Started at 25mg the first month - no effect. Moved to 50mg for another month - no effect. Taking this is like taking a sugar pill. For 1/10th the cost, I can go back to oxybutynin and regain control. I liked the absence of the dry mouth, but the absence of the control is worse. I say "no effect", but it did seem slightly better than taking nothing at all, so I gave it a 2."
