Becca71, My experience and opinion matches what you posted. Also, I get great sleep....GREAT SLEEP.....and most of the time. Sure, there are those nights we all have, but I am self employed and able to catch up when they happen and after I get symptoms under control. Then, for the rest of the time, I sleep until I wake up, which is usually around 9 hours each night (my meds sort of knock me out, Im sure, but regardless, I sleep like the dead!).

And....I have those symptoms you mentioned (cognitive, all of them).

Its strange to me that for those with Fibromyalgia, they call it "fibrofog" and it's widely accepted as a part of that condition. I have heard some doctors say that CRPS is an extremely advanced case of Fibromyalgia, and while I have no idea if they're right or not, this part of Fibromyalgia is also experienced by those of us with CRPS.
I was diagnosed with Fibromyalgia long before I got the CRPS, fwiw....and I have no idea if I have both conditions, because the CRPS overrides the Fibro and has since day 1 of having it....I never think about Fibro anymore even though my entire body hurts....but in all limbs I have the CRPS, so I do wonder when some CRPS doctors say the two are related.
