overactive bladde
"Toviaz worked very well for the first few weeks, but then started losing its effectiveness.  I used to wake up 10 times a night to use the bathroom and now I get up around 5 times a night.  It causes dry mouth (which is especially bad during the night) and also makes me tired.  Also, the best insurance plans typically won't cover this medication (I pay $70 for one month supply)."
