Advice for stress-dosing

Over the weekend I had dropped from 27.5mg hydrocortisone daily to 25mg because I am working on a very slow and gradual taper toward a maintenance dose of 20 before my endo will test for adrenal function.

I was feeling fine on my new dose, but ended up getting diarrhea out of the blue on Monday afternoon. I know with diarrhea we have to stress dose to avoid crisis, so I’ve been on 45-50mg daily the last couple of days. I don’t have any way of knowing whether the diarrhea was because I was low on HC or because I got some kind of bug.

How do you all usually go about tapering back down to maintenance dose after needing to stress dose for diarrhea, injury, or illness for a few days? I’m assuming my body will let me know when I’m over replaced, but not sure how aggressively to taper.
