overactive bladde
"I have been on this medication for 2 months--50 mg.  It has reduced my frequency slightly (from 20 to 18 times), but has relieved the bladder pressure and urgency (that was constant).  I can almost sleep for 5 hrs without the need to urinate.  It has significantly improved the quality of my life. When I started the medication I had headaches, but after a week they disappeared."
