Mirabegron
overactive bladde
"I've always experienced frequent urination, particularly annoyingly at night. Recently it has coupled with nighttime anxiety to perpetuate sleep maintenance insomnia. 
I gave Oxybutinin a try, but the dry mouth was unbearable. 
Mirabergon however isn't any better in terms of side effects. After one day, I have a cold and headache, and am dealing with highly unpleasant urinary retention. I can't continue. 
I recommend stringent 3 to 4 hour fluid restriction prior to bedtime and Desmopressin for anyone dealing with nocturia. They will help at least a little. But the anxiety must be dealt with as well to fall back asleep upon awakening."
