Overactive bladder, treatment not working, peeing nonstop?

at night i get up like even up to 10 times to urinate, seen urologist alot, their treatments arent working, had several UTI's, took antibiotics, antibiotics not working, symptoms never went away, took ditropan and it does not stop the frequent urination. i keep peeing nonstop and it never feels like i'm done. what problem is this? am i right that this is overactive bladder? no pain or blood. Do u know anyone who suffers overactive bladder and goes as much as me? do u know any strong medications that is effective in stopping the frequent urination? the doctors dont seem to care and their treatments arent working at all.
