Susan, I don’t know anything about your medical issues but if you are drinking over a gallon of water and still thirsty, there may be a treatable issue. Drinking so much may be flushing your electrolytes and keeping your body from absorbing and utilizing so much water.

“ Staying hydrated requires more than just water. Electrolytes and carbohydrates also play important roles in absorbing fluids. Additionally, electrolytes—sodium, chloride, potassium, magnesium, and calcium—are vitally important for healthy nerve and muscle function.”

Hi. I drink at least a gallon of water per day. I was always a thirsty person. I told my doctor this and he told me it was great. He said my constant thirst is related in part to Hashimotos. When I was a kid I got laughed at because I was constantly drinking. (I was not dxed with thyroid issues until much later in life). Add a bit of coffee and some soda to that gallon lol! Seltzer and OJ is delicious.
