...and if this helps any, maybe it will maybe it won't.
I remember a post a while back Uny where you talked to Joseph about weaning his HC and you told him that when you make too large of a cut and yo-yo the dose, you have to end up increasing your original dosage to avoid damage to the adrenals.
This past summer, I had a period where I attempted weaning my HC, not quickly, went from 20-17.5-15... and distinctly remember after a few weeks I was back at my original dose of HC at 20mg and haven't really felt the same since. Longshot I know, but just trying to throw something out there.
