overactive bladde
"Have used this for 3-1/2 years.  It seemed to lose effectiveness after 2-1/2 years.   But it is still helpful.  I still go frequently and get up 2-3 times at night (vs 3-4 times), but it takes "the edge off" and I can wait longer and feel less urgency.  I take 5mg at night.  I've stopped taking it for 60 days at a time on two separate occassions and I can clearly see the medicine helps a lot."
