Have you done a 24 hour salivary cortisol test? I saw you mentioned that your cortisol went sky high early last year when you were trying the b12 protocols -- that would indicate that indeed your adrenals are still able to produce cortisol, and are perhaps overproducing it at times, so you would NOT want to take any sort of supplement that increases cortisol (like licorice, etc) and may indeed need something like Seriphos (that will temporarily lower it, and help reestabilish normal circaidian rythym (sp).
There's a huge difference between adrenal burnout (which it sounds like you're in) and adrenal 'fatigue' or 'insufficiency'. Burnout comes before the latter two, and so it would be dangerous to use any sort of cortisone or other cortisol raising supplement at this time. You've got enough. Just have to re-regulated it.
