, do you have pain in urination or after urination, any burning sensation in urine and hows your problem starts?
According to you mail it seem that you have overactive bladder
but needs to be proved. Try some precautions like retain urine as much as you can and than urinate, it is the best exercise of urinary bladder, take less amount of water in evening so that you get less urine at night.
