Answer 1

I don't know how old you are, but if you had the Prostate Surgery (probably the TURP), it takes a long time to return to the way you were. The longer your prostate was enlarged, the longer it will take to return to something near normal.
I just had this surgery a few months ago myself and I still run to the bathroom every few hours. My doctor told me that the bladder and muscles were overworked from the enlarged prostate and that it might take as much as a year to recover completely.
The actual operation probably allowed you to go to the bathroom normally again. You probably don't have any leaking or slow stream or etc.
Unfortunately, caffeine, cola and other drinks irritate the bladder more now because it is in a healing state. Try drinking more water, Gatorade, juices, etc. You will be pleasantly surprised at the outcome because the bladder will not be irritated as much and you will be going less.
Good luck!
