overactive bladde
"I had a very severe bladder infection that caused bladder spasms, so my doctor gave me samples of the 4 mg Toviaz.  It definitely worked.  I was able to urinate only when needed, and was not running to the bathroom every time I took a few sips of liquid.  I was actually able to make it through 6 hours of sleep!  My only problem is that after about 12 hours the urges to urinate begin to increase again.  I wish they had a shorter acting product that could be taken every 12 hours instead of every 24, because my body seems to metabolize it very quickly.  It would be nice to take it when I got up and again in the evening.  "
