I 27f and have central diabetes insipidus secondary to a pituitary adenoma, for which I take daily desmopressin 60 �g, I also have hashimoto's for which I take levothyroxine (25 �g for now. I haven't been feeling well lately, anxiety, irritability and headaches has been at an all-time high, with an inability to fall a sleep I was wondering if this may be due to severe dehydration and hypernatremia, and I would like to know if not drinking water will cause any damage in my case. Thank you.
