I don't know I can say I am cured but at least, most of my symptoms are gone. I still have GI issues and when I started the drug, I had stomach pain, some nausea, sweats, a headache. Since I wrote my description, those things have improved. I have IC, too, a bladder condition, and I think my frequency has increased. Otherwise, I'm awesome - walking again, exercise class, able to get up in morning before 10 am, no naps. Feels so good. I would recommend doing the actual Tilt Test - I had tried doing it at home, too, but it's nothing like the real thing....not that much fun but now, I can say, it was worth it. Hope that helps.
