Thanks! I don't see anything new there, but I'm interested in the inclusion of 'orthostatic intolerance', as it's a hypothyroid symptom which I don't remember previously seeing on conventional CFS symptom lists.

The alternative types all seem to blame 'adrenal fatigue' for it. I think they think the adrenal glands wear out from over-use.

From my point of view there could either be underactivity of the adrenal glands directly caused by hypothyroidism (it wrecks everything), or 'peripheral resistance to adrenal hormones' caused by whatever is causing the thyroid resistance / insulin resistance.

It certainly tallies with my experience. I found for years that I'd feel dizzy if i stood up quickly, sometimes to the point of nearly fainting. It was put down to low blood pressure, so it was a bit of a surprise when I found that my blood pressure had gone slightly high but it was still happening. All fixed now.
