HELP, OAB 1 year after prostatectomy

I had a radical laparoscopic prostatectomy with nerve sparing on 7/11/18 to remove prostate cancer. Thankfully, I am cancer free with a PSA of .01. So why am I complaining? Today almost no leak, no pad all systems recovered. Thank goodness.

Currently I seem to be going through an overactive bladder period for some reason which reminds me of my enlarged prostate days. Now I am getting up at night 2-3 times instead of 4-5 prior to surgery, almost had it down to 1 time. During the day I can hold it for 1 1/2 to 2 hours then some days it's only 1 hour. I don't drink or smoke, taking no meds of any type only vitamins. I know the drill from enlarged prostate days of what to and not to drink and eat.

Prior to surgery Merbytric worked great at $70 per 3 mths but now its $350 per 30 days thanks to Medicare. I really don't want to get hooked on a drug I would rather find a good herbal product. If anyone has any suggestions I would really appreciate your help. Thanks, TW

My problem, that was similar in nature & came after laparoscopic (colon) surgery was due to a stricture in my urethra not my prostate issue. Thankful they found my PCa before they found out what the real problem was (I guess) Not saying that's your case, but it was for me. It does get me to thinking though, If you don't smoke, drink or do drugs, what do you do for fun?

I found that coffee, both regular and decaf, caused me bladder spasms after prostatectomy. Tea doesn't cause any problems.
