I too am on beta blockers and have resisted RAI treatment. I have taken the meds for hyperT but have become allergic. (low white blood cell count & severe burn like rash). I have used variouis herbal combinations (bugleweed, motherwort, lemon balm, passion flower, valerian root) I took this combo for 2 years, with ok results but not quite good enough. I've also have had acupuncture treatments regularly, which helped alot.
The hair analysis sounds like a good way to go. I'm going to look into it. There has to be something natural that works and there has to be a cause for this dis-ease.
We can't give up!
