I'll let others suggest. You don't list not doing intake interviews as one possible accommodation, and I assume that's because it's either impossible to have your assignments changed in that way, or not something you want to give up. But under ADA, "Reasonable accommodation is any change or adjustment to a job or work environment . . . . For example, reasonable accommodation may include . . . job restructuring . . ."
And I'm sorry to take this in the direction you didn't want to go, in a way that I'm sure will irritate you, but "knowing about D3" and "understanding busting" are not the same as doing them, and ultimately, not having chronic CH is the only way you're going to restore your ability to do this work in the way you want to do it, and D3 and busting have shown themselves to be the best ways that I know of to accomplish that.
Since you've made clear that none of this is what you are asking for, you don't need to reply. As I say, I hope others will make more of the kinds of suggestions you are looking for. Best wishes.
