Okay I'm coming into this thread 7 years late but I've been referred to Dr O'Callaghan and I have severe CFS. Are you saying he's involved with Emerge?
did you see o'callaghan yet? i'm on the pills he prescribes right now and I have to say they work for me. the only problem is he won't prescribe them in perpetuity and i'm not looking forward to coming off them.
my take is o'callaghan is less rigid than he has seemed. yes ,he believes in exzercise, and yes, he will tell you to expect to improve permanently. but i have heard he's willing to let people just take the pills. And as far as the second one goes, I guess it's just him trying to will a permanent fix into existence. might as well play along, can't hurt to try to believe it! if you have pots-type symptoms, midodrine can be pretty amazing.
