Over the last 6 months, I have been having 2-3 day episodes of incredible amounts of urination. I urinate huge volumes of water all day, without drinking excessive amounts of fluid. Usually stops at night. This will last a couple days, then I will feel fine. During these periods, I feel very poorly--lightheaded, weak, sometimes have chest discomfort. I have been to 6 doctors and nobody has a clue what is wrong with me. Any ideas/suggestions would be appreciated.View Thread
