I have the same problem. I have nights where I get up almost every hour to go to the bathroom. I have been to a urologist and they didn't find anything wrong with me. He seemed to think it was related to stress.
Have you gone to see a doctor about this? If not, in my opinion, you should go and have it checked out...it could be anxiety and it could be something simple to treat. Never hurts getting it checked out. Keep us posted
if a peace of mind your looking for, you came to the right pleace. i had the same problem, i try not to drink anything at night, but i still have to wake up one or two times a night to go. even in the day time i find myself going more often then before. but it has pasted for me and it will pass for you too
