Welcome Jim,
This is a great site, and if we members haven't experienced something or don't know the answer, Brian probably does. I found this site shortly after finishing my chemo/radiation therapy , when I was at my lowest. I found no real support at M.D. Anderson, but I found plenty here.
Sounds like you have been through a lot. Keep us posted. By the way, a PEG is nothing. I have played golf, worked, and done just about everything else with mine. I am soon to get rid of it, but even now when I can eat quite a few things, it is still easier sometimes just to hook it up and get my nutrition in a relaxing way.
Good luck,
Danny G.
