@abopp2022 as I said and others said a medical check up with another doctor is a good idea. You should not be excessively thirsty when you are drinking a lot. You should be getting a minimum of 40-50 ounces of water each day. Caffeine is a dehydrator so if you have that in your diet, you will need to drink about 70-80 ounces a day. If you are drinking these amounts and are still thirsty, please see a doctor about this.
