Hi Julie, I had this problem, still get tired quickly and can fall asleep easily when I sit done – even on the loo!! It was put down to low calcium originally, which was put right to an extent by meds, I also had low ( 8 ) heamoglobin. this is now up in the 10s, still a bit low but I feel so much more energetic, and am able to do 3 – 4 hours activity, with a break. Hope this is some help, Jeff
