Ever heard of water deficiency apnea? I crave water @ night. Usually drink 1/2-1 gallon a night. Concerns me because i wont urinate but maybe once the night & wake up swollen, especially my face & eyes. My calcium levels stay on the high end, so my dr. Decided to start screening me for lung , laryngeal , & esophageal cancer every couple of yrs. she says high calcium levels can be a precursor to certain cancers...? Dont know if its even relevent, but i have psoriasis & have problems w low blood sugar regularly (its pancreatic, i just produce too much insulin). Im 25, white, female, 5 2 , 200lb. YYYY@YYYY
