Off and but now for three straight days and nights after drinking water I am urinating every 10 to 15 min. Associated with this is lots of dizzyness and light headed and feelings of fainting. I drink 2qts + of water and vitamin water and gatorade. It is so bad now that UTI's are popping up. With the UTI when I stopped the diuretic the frequent urination stops. when I take the HCTZ it starts again. I have been on this med. since 2003. I am exhausted trying to keep up and I feel drained of all nutrients etc... Recently trolly horse type spasms in kidney back area. I have had test and I am not Diabetic, I am Anemic but taking iron, I take 25 mg of Cozaar for HBP and I have no side effects with it. The standard blood test show No Tyroid problem. I cannot keep hydrated and I am constanly dehydrated and now my body feels weak from all of this. What can this be? Is there a better diurectic? What is your take on dandelion root? Somebody Help!!!!!
