I've just been notified of a book on this subject, which seems to be a common part of ME. I haven't read it yet. It's by Patrick Ussher, who, like me, suffers from ME and polydipsia. It can be downloaded free here: https://www.themythofprimarypolydipsia.com/ Extract: "The tendency of medicine to suggest that symptoms it does not yet understand are psychosomatic has a long history and one that rarely ages well: Parkinson’s, MS and ME patients, among others, have all had to face this kind of stigma. This book argues that patients with so-called “Primary Polydipsia” fall into the same category. These patients are not mentally ill. Rather, their bodies scream with a thirst that is very real and which carries a serious risk of neurological injury and fatality. This book is therefore a clarion call for doctors and medical researchers to return to the drawing board and to reconsider Primary Polydipsia with fresh eyes so that the very sick can, at last, be treated effectively and compassionately by the doctors to whom they turn for help."
