Sleepy I thought iron can make you constipated not give you the runs, it does sound like your body may not be absorbing it? I'd go back to your dr straight away? Hope it all settles down for you... My headaches have stopped now, maybe my iron is slowly creeping up to an exceptable range.

Thanks so much for everyone for posting in this thread, it does seem like low iron is a valid reason for the headaches considering 3 of us all have/had low iron.
