I don’t know if this info will help anyone but here goes. So I ended up in this totally backwards from everybody else. There is an autonomic nerve disorder Baroreflex Disorder that is caused by damage to the Vagus nerve cluster in your neck and that is the only way to get it (I had a benign tumor removed and the Dr. hit the Vagus nerves in my neck). It extremely rare as in only 2 places in the US do diagnostics so I got to go to Mayo. I am going on 11 years w/ it and it has caused all sorts of issues including Gastroparesis (new drug Motegrity is a big help). So if you are investigating what Vagus nerve issues can look like you could take a look @ Baroreflex disorder only downside is present research info does not cover all possible problems and their is no ongoing research on it. It is too rare so not good at attracting research $. The only medication that minimizes it’s impact is clonidine and in fact the final definitive on diagnosis is if clonidine helps that is what you are dealing with. Whether it would help w/ damage due to T1 I really do not know but might be worth trying. Also I am LADA which got diagnosed 2 years ago @ age 59 after years of your T2 when turns out I wasn’t. Hence my comment that I am coming at this backwards.
