I was going to say what Bug's Mum said - I had huge difficulties breathing from doing minor activities - it would make me really puffed.

Iron deficiency also left me feeling light headed at times and incredibly tired. I could sleep anywhere and everywhere. I didn't realise what my symptoms were so it got quite bad after a few weeks and I could fall asleep without meaning to. I was meant to be supervising DD1 and I would just fall asleep and not much would wake me. I felt so incredible and energised once I was on iron tablets.
