Hey goten, how did you make out? Your symptoms are pretty much identical to mine. I have been drinking RO water for years now, and before that I never drank much water, so I am wondering if this has something to do with being dehydrated for long periods of time.
I really think my has something to do with the prostate, although like you, my has been checked for infection and enlargment with nothing being found. I have also had ultra sounds on my bladder kidneys and nothing out of the ordinary was found there either. Anyway let me know if you are still around and how your doing?
