Hi SanDiego,
I have not seen Dr. Cheney. I can tell you I do NOT agree with
Dr. Paul Cheney Discusses the Benefits of Klonopin. Having been on Klonopin for about 25+ years and now slowly - slowly coming off of it, and being Dx'd with CFS while on it, I see no need to be exuberant about its use. Why not Lamotrigine if concerned about seizures/seizure related states, or one of the many other anti-seizure meds that are not addictive/habit forming (depending on who you talk to about addictive vs habit forming). Just sends up a red flag for me.
But more to your point, if I were having Cardiac issues, I would see a cardiologist and if not 100% satisfied with one, get a 2nd opinion from another, etc. Not sure if you are using Cheney as a primary? I have heard some good things about Dr Flechas (M.D., M.P.H) in Hendersonville, just a short way from Asheville. He advertizes as an Integrative Internist. I think much of the CFS treatment comes down to managing your doctors, questioning everything, and not being afraid to move on or around when one doctor does not have all your answers.
