I took it for over a year and with my insurance it was $160 for a three month supply. Then my contribution for a refill went up to $900 and I stopped taking it only to realize it was not doing all that much anyway. I am four years post radiation treatment and I am not having accidents wetting myself. But I can't wash the car, do the dishes or pour liquids without an emergency run to the bathroom. You learn to deal with it and it get's easier.
