See you doc and get tested for Diabetes Insipidus

Avalide side effect is dry mouth and excessive thirst. Perhaps your doc should rethink and rx another blood pressure med.
Any other medications you're on that you didn't tell us about?
First of all DO NOT force yourself not to drink. That will increase the probability of a stroke. Absolutely and positively the WRONG course of action.
When insulin is not available, the body goes into an "alternate mode" to deal with the blood sugar. For this to work a large amount of fluid is required.
You neeed to get together with your physician, or a diabetic clinic, and for a short intense period of time, get your diabetes under control.
There are other possibilities for the thirstiness, but, "mother nature never does nuthin' for nuthin' " as a famous physician friend once told me.
His first rule was "Do not interfere with compensatory mechanisms", and the thirst is there for a reason.
You need a good evaluation at a teaching hospital.
Get off avalide. I have been extremely thirsty and have been off the drug 10days and still have the thirst. I am diabetic and sugars are betwwen 5 and 10 so I am good. Going back to the dr friday
Hi! I have Type 2 Diabetes and one major symptom for me was extreme thirst and urinating, so it does sound like diabetes to me. Have you had an A1C test done? That tests your storage glucose over a 3 (or 6) month period. Ask your dr for one, the name for it is HA1C (that is short for Hemoglobin A1C) Good luck to you!
