My question: I have to urinate all two hours in the night, I go to bed at 11:00, have to got to the toilett at 1:00, at 3:00 at 5:00 at 7:00 rise up at 9:00 and I m still terrible tired. They want to put me now in a sleep clinik, they told me (after they checked my blood) I have no kidney problem, no diabetis 2 problem, no water in the legs. My blood preasure is good, my cholesterin is good, my brain is o.k., I m 74 years old. What is the rason to go so often to the toilett. At night I produce 1 to 1.5 liter urine, (all together), durig the day only 1/2 liter.
