Thank you lotus for all the data and links.

I have become increasingly aware that endocrinology is a horrendously complex field, about which I know far too little and in which multiple interactions produce unexpected and non-instinctive results. Some people seem to be able to see ways through the maze, but I am not one of them. I try my best to find what works for or on me and other people, and try to pass on what possibly useful information or observations I find along the way, but you seem to be producing treasure trove? The query because I suspect that I will end up even more bewildered.
