I don't have any definitive answers. All I can tell you is, if you felt as lousy as I feel, you'd be willing to try it given the lack of any meaningful treatment options from the current mainstream medicine that has managed to extract a shitload of my money in exchange for mostly blank stares & shoulder shrugs (or my favorite, passing me onto another specialty, resulting in another 2 month wait.)
