Hi again and thanks all for your info. I have had complete cardiac, neuro, and endocrine work ups, they ruled out pheo and carcinoid. Ive had tilt table (and failed it big time), ekg's, eegs, CT,s MRI, endoscope (both ends woo hoo), plasma mets test from mayo, thyroid, and a bazillion other blood tests. I am currently taking Toprol XL, which makes me feel tired and crappy, synthroid even though my thyroid is normal, protonix, reglan, and I have marinol, klonopin, valium and a bunch of nausea meds. If I took all the meds they gave me Id be in bed in a coma. I am going to see a Dr. Newby at Duke in Durham NC on May 16th. She is suposed to know about neurally mediated hypertension and POTS. So we shall see. Thanks again for all your support, it is greatly appreciated. Janine
