overactive bladde
"I have multiple sclerosis and one of the most annoying symptoms is urinary issues.  I have to go A LOT, don't have a lot of time to actually get to the bathroom and I wake up 4-5 times per night to go.  I have tried a few other medicines for this but Oxybutynin ER has been the only one that made a difference.  Now I only get up 1-2 times per night and I can go out without fear of finding a bathroom in time. Only side effect I've had is severe dry mouth, but it does make me drink more water so not a total negative."
