Yes, I am, anaemia too!
I actually find it absolutely fine. I feel less sluggish most days. Down Days are quite energising, oddly. Up Days are the ones that make me feel most bloated and flat, slow and uncomfortable.
I can honestly say that it has not made the CFS any worse, though I am finding that the lack of sunlight and cold weather has made me feel less like continuing regularly. So I pick very highly flavoured, hot foods on all days, just so I can savour every mouthful. I really feel the need to know I have eaten, even if I don't really miss the calories.
Are you trying it/worried about it?
