Deucykub, Thanks for the information and the link. From what you said and reading the link, it sounds like it is the neurally mediated type of hypotension. This fits with my experience of finding that benzodiazapams help me with stamina and chest pain, (currently taking low-dose klonopin) as I've read that they are only helpful if the problem is neurally mediated. I also find that the speedy fall in BP usually comes after I've been standing for a few minutes and I've always had enough warning time to sit down. Symptoms have varied a great deal over the years--pretty functional periods and sometimes pretty non-functional--but I've only found a knowledgeable doctor whose known how to treat it in the last year. I've tried and not been able to tolerate florinof, midodrine, and clonodine, but the combo I'm taking now is working pretty well--I'm so grateful. Particularly the stattera and cymbalta stabilize my BP. Thanks again.
