Hi,
everything is getting really busy for me, could you plese email me (mslarsen@wisc.edu) and we can talk in more detail. It's just that coming and finding the place in the forums where I last posted to see if there is a response takes so long. In the mean time you can find pretty much all the info in a book called "sick and tired? Reclaim your inner terrain" by Dr. Robert O. Young. Talk to you soon, and best of health, Mike
