I don't know much about hyperadrenalism as I have the reverse problem, but I do know there are supplements you can take for it, such as phosphatidylserine. The danger is that his adrenals will wear themselves out. But I would get his cortisol and catecholamine levels tested before doing anything. Reducing stress would be the first line of defense. And avoiding all sources of caffeine; does he drink a lot of coca cola or eat a lot of chocolate?
Thanks Deotima, I happen to have some astralagus, so I will try it. I have been drinking coconut water and juice with Seasalt to rehydrate. That's my only concern, how much the Epsom Salts dehydrate me. But as I am still feeling very sick I have no choice but to try another flush tomorrow--my plane tickets are non-refundable!
