I've successfully made it through my first day w/o gluten. As far as the iron infusions are concerned, in what time frame did you have all of them? Were your ferritin levels checked after each infusion? I had one, waited two weeks and had a second. When they tested my ferritin, it was well above the minimum. Then, it appeared to have bottomed out. As far as the lethargy is concerned, I didn't really feel better once my ferritin was elevated. I am curious to know what your experience was with it and how they monitored it.
I had 7 iron infusions over 7 weeks. They will check my bloodwork 5 weeks after my last infusion.
