Gerard, thank you very much. I've been on a completely no dairy and low starch diet since February, and had been feeling much better than I have in years (not completely pain free except for one day, but a billion times better). Until my roomie forgot about the no dairy, low starch thing and made me mashed potatoes with butter and cream. Not realizing that he hadn't used margarine, I ate the mashed potatoes and, well, I'm still recovering six weeks later (although the worst of it was over within about three weeks).
Thanks again.
Kat
