Thank you so much fleur. I suspect there's no problem with my adrenals after the energy I had yesterday! Still lots of pain though. I wonder if it's the ACTH but I guess will have to wait to find out. The not feeling hungry is very odd for me though.
Cat - well apparently not according to tests- I have too many red blood cells (out of range upper) though the ferritin was 57 when tested. Although, when I was tested I'd felt a bit better and eaten buckets of red meat over the weekend.
What I have noticed it the rls gets worse with caffeine and I tried Epsom salts yesterday and felt a little better. But my magnesium was fine.
I keep questioning b12 and PA but the lab wouldn't do the b12 based on my rbc and Dr thinks they've checked the size though I'm actually not sure. Going to look at the results again. I'm going to ask for an intrinsic factor test as my aunt has PA.
PERSONALLY I feel that I lost so much muscle through physical and mental stress as well as not quite enough thyroxine due to the sertraline (I've found a study showing it reduced thyroxine and it's listed in the bmj thyroid patient book) that during recovery I've become transiently aneamic at times. Muscles need iron to regrow. ALSO sertraline will make rls worse. Low thyroid hormones affect the proximal muscles. I've also had so many infections this year plus a bad vomiting one. They will have used extra iron. PLUS I'm small and hypermobile.
I can't help thinking that lactation might be altering the rbc. I guess the lactation might also be making things harder,
though I don't have periods back yet either so they'd be an extra out put too.
But drs keep looking blank when I say this. 
At the same time, I don't really eat anything that isn't full of iron or folate or b12!!! I bought some ferriglobe or what ever it is yesterday.
I just want to feel normal again :(
I lost some sensation in my hands and feet after the rls got really bad and it feels like the tip of my tongue is numb too.
