Alex1 - normally I can stick to my diet without too much pain or feelings of deprivation, but somehow over Christmas it all got much worse. I also had a big six-month post amalgam mercury dump - the worst so far - and felt absolutely terrible for a week. I didn't want to be me - I wanted to leave everyone and be someone else. I SO wanted to eat cheese and chocolate and have a cup of tea with milk, and actually did sneak a few pieces of cheese when I really really couldn;t handle it. I'm back on the straight and narrow now. By the way, I'm an ISFJ!! How funny you know about that.

Bex - thanks for your comments. I think you may be right that its the quantity of sulfur foods which matters. Hard-boiled eggs seem to give me a problem, and when I have them with cabbage soup I am definitely in trouble. But a 2 egg omelette for breakfast seems to work. Still can't quite get my head around the sulfur thing - surely it's good to mobilise the mercury and get it out? I have a liver condition which sulfur foods are supposed to be very good for, so its confusing.
Anyway, onwards and hopefully upwards.
