I agree with your positive sentiments regarding Curezone and OPing!!!
I, too, have a long history with bladder/urinary problems (my bladder ruptured and was repaired - followed by prolapse - still have occasional issues with incontinence, and UTI's are common)... yet another recurrent issue I'll probably live with forever, but I'm not complaining.
I have found that, of course, increasing water intake helps. I also drink Rosehips Tea ... eat lots of asparagus, garlic, and parsley ... and make sure I get plenty Vitamin C.
I've heard that Juniper Berries are excellent for urinary tract health, too ... but I've not personally tried it.
