I Had My Prostate Removed In 2010 Robotically. Now At

I had my prostate removed in 2010 robotically. Now at 65, I am up about every 2hrs urinating only at night. I don't have any pain and I am not diabetic. I have high blood pressure and the medication that I take is Amlodipine besylate 10 mg once a day and losartan 100 mg, once a day. I have been taken these 2 for more than 2 years. My new house of 2 yrs. Keeps me pretty busy and I am a student of tai chi for more than 20yrs. I have gotten away from juicing and would like to know if I start it up again, what can I take to stop the frequent urination. Don't know if my kidneys or blatter are developing a problem. Can you help???
