Howdy!

Sorry to hear of your Coeliac diagnosis A. My brother and a close friend have it too, it can be so painful.

RE: folate, Dr Google says no - that there are no known toxic effects from having too much. However one FAQ I saw mentioned a National Health and Medical Research Council recommended a limit of 1mg/day. I'm no health professional though!

Have you ever seen a naturopath and/or a dietician? If not, might be worth checking out. I know it's much milder but I have Irritable Bowel Syndrome and seeing a dietician really saved me.
