Trospium
"My urologist prescribed this 3 years ago and gave me samples to try.  It was amazing!  It worked so well it seemed like magic. I am just thrilled with the results.  While I still get up during the night, I don't have the worry of not getting to the bathroom before the urine drips down my leg.  In addition, I don't get up as often, which gives me a much better quality sleep.  During the day, my overactive bladder has calmed to the point where I feel normal!  I'm so grateful to have this medicine. It has changed my life."
