My doctors have told me OAB means you urinate frequently, which I certainly do, every 5-20 minutes, 24/7. Once in a while I make it to 60 minutes. When I was at my sickest with COVID, I couldn’t tolerate eating or drinking. I lost six pounds in seven days. I drank less than 20 oz. per day and hardly peed. I slept great at night, for a change - only woke up 1-2x per night to pee. Too bad dehydration isn’t healthy - then again, neither is not sleeping.
