Dear Susan, I take 60 mg. of hydrocortisone daily -- 40 mg AM, 20 mg PM.  After much trial and error, this works best for me.  I’ve learned on this site that 60 mg. is a high daily dose, but my 17 0HP levels have always shown me to be under-suppressed -- meaning that I would need to take more to truly balance out my levels, but that would heighten the risks from long-term steroid use, so I keep my dose where it is. 

It’s worth mentioning that I freely give myself stress-doses when I feel it’s needed.  After 40 years of living with CAH, I’ve gotten to know my body pretty well.  I can feel when I’m starting to run low and simply take an some extra.

Hope this helps -- Eric
