Ah, I should have been more clear about the role of cortisol and T3 - I am severely hypothyroid due to Hashimoto’s, so I take time-release T3 for thyroid hormone replacement. T3 requires cortisol to get into the cells - indeed, if I don’t take enough cortisol, I end up converting the T3 to reverse T3 and hypothyroid symptoms return.
I still have functioning adrenals, but CFS patients tend to have strange hypothalamus-pituitary-adrenal axis dysfunction. In my case, I tend to relative hypocortisolism during the day, and hypercortisolism at night (disrupting sleep). Taking small amounts of cortisol during the day helps balance out this response, possibly by bridging a broken HPA feedback loop. I also have trouble maintaining optimal salt balance and blood pressure despite seemingly normal ACTH, which is why I take small amounts of fludro (or eat huge amounts of salt, ugh).
I suspect that my problems with the stress response stem not from cortisol secretion, but from norepinephrine. I actually feel pretty great during the response - my brain clears up, nervous energy fills my body - but the response doesn’t end until it basically empties my energy reserves, crashing me. The catch-22 seems to be that when my energy reserves are higher, I can stay in fight-or-flight mode for longer, making the crash all the worse. If I’m drained to begin with, the response has little left to take.
I am considering the possibility that I simply have trouble generating energy efficiently from glycolysis or lipolysis, but that’s going to take a lot more research…
At any rate, NAC seems to be a bust so far, l-tyrosine makes only a very small difference, and NADH makes me sleepy. Only b-vitamins, creatine, DHEA and pregnenolone have a reliable effect on my energy levels. I’ll have to give PS a try and see what effect it has. SCIENCE! ![]()
