At bedtime, my mouth becomes really dry and I have uncontrollable thirst. Per my latest labwork done, no, I don't have diabetes. Also, I don't drink alot of water because my Fibro causes frequent urination-----------I can't run to the restroom every 5 minutes on the job. I often urinate 5 to 20 times overnight, having to get out of bed, if I give in to my dry mouth and uncontrollable thirst. Any suggestions/ideas? Is there another test that can reveal diabetes? Might I have something else?
