I agree with everyone about the rest, in fact it took me a LOOONG time for that to sink in and I did not start to improve until I started resting more and doing less. Looking back on the last 2 years, rest was the most important thing of all the things I tried.

I still have setbacks, but guess what?...Only when I am not rested!

Mark's analogy was great. Sometimes I think of it as a broken bone with a cast on it...you are forced to rest that bone until it heals, the cast keeps it constantly resting while it heals. We have to do a self imposed cast and through trial and error learn how much is too much.
