DEAR DR. GOTT: I urinate four to five times a night and almost every hour or more during the day. I have seen urologists and have been tested, with negative results. My body and prostate are OK. I have high blood pressure, which is under control with Norvasc. I have tried all kinds of prescription medicine: Sanctura, Toviaz, Uroxatral, Elmiron, Hyomax, imipramine, amitriptyline. I am currently taking DDAVP. Nothing has worked. I had various bladder and kidney tests. What do you suggest? I have to be careful when I travel, and I love to travel. Thank you.
