SORRY - I think I got your userID confused with someone else who commented in another thread. Some of my comments were based on having strictures, which I now see was someone else (another mommyof2...) I apologize for the confusion.
You should also run any increase in iron (either via multivitamin or supplement) by your doctor. I had my iron supplement increased before we realized how severe my strictures were, and it really bound me up and led to a lot of pain.
