I actually started on about 20 mg HC after a year of failing with natural therapies. I was severely bedridden for a long time after a major crash, so I really had no choice.
Now I am at around 7.5 mg. I cut down 1.25 mg a week. If I go below this I do very bad. I introduced ACE drops last year and am hoping to start to build up my adrenal reserve. Pregnenolone, Vit C, B vitamins are way too stimulating for me. At this time ACE drops and HC are the only 2 things that work.
I don't know your story or how bad you are but I only resorted to HC b/c could barely move. It scares me when I cannot go below the 7 mg dosing to be honest. I hope as time goes by and my adrenal integrity rises, I will be able to taper down.
What have you tried, what stage of exhaustion are you in?
