SB - I am taking about 200 mcg of molybendum per day (however much that is?). I have taken much more without noticeable ill effects though.
I have eaten a little avacado here and there and I do fine, but I definitely notice if I have it a couple of days in a row.
Just stop the limcomin for good IMO, I am really convinced that both of us just cannot tolerate copper. Maybe we have minor Wilson's or we are pylorric or something. Outside of NB there are plenty of people/practitioners that get people off of anything copper related permanently, for some reason NB does not seem to adjust for some people being unable to tolerate any copper.
Good luck, I am doing much better after quitting all copper and supplementing the other nutrients in Limcomin with Citramins II.
