Do you have the same problem? Is there anything I can do about it? For a while I thought I just had a small bladder measuring the amount I urinate showed normal values of roughly 500-600 ml when waking up with a stronge urge to pee. This does make sense to me because the 3 to 4 liters from drinking plus the extra water from food has to go somewhere after all, so I am wondering why other people do not have this problem.
