Like as soon as I drink my mouth still feels incredibly dry, but I still pee it out soon after (often the urine looks just like water). Bear in mind, I have other cfs symptoms too, including fatigue, stiff-feeling neck, diarrheoa, weird gut noises, headaches, tinnitus. Is this thirst problem serious? It feels really bad. What could it mean? Any treatments/cures? Note I do not pee at night.
