I am a 17-year old male who has had excessive thirst and urination for as long as I can remember. Until about 12 or 13 I was an uncontrollable bed-wetter. These problems don't seem as bad as they used to be, but they are still there. I also have frequent dry hands, occasional shakiness and weakness, and almost passed out once until I ate a sandwich. Sometimes bad memory accompanies these symptoms. The dry hands used to be much more severe than now. I also usually have cold feet, and in the winter, hands. I've been suspecting hypoglycemia or diabetes insipidus.
