Most of the problems you are having is due to your diet change and activity change(possibly). You immune system is down because it is trying to battle the gut which is being forced to have items digested that it doesn't want to digest. Your diet for the past few years has not included some things and your body has enjoyed it. Now that you are reintroducing grains and meat, your body is trying to switch over and is not winning. Also, when you go from high activity to low activity, your body still produces adrenalin each day after you stop the high energy cycle as if you were continuing. If you don't train down, then that adrenalin accumulates and you end up feeling terrible, tired all the time, and depressed without having a reason for it.
The solution is to allow your body to recover. Get back to eating right and allow your immune system to increase without having to battle energy with all the other stuff. Whether you rest and allow the immune system to recover or begin to SLOWLY increase your activity to get it going again depends upon how your body responds. If you start to go to a workout and your body is saying it doesn't want to, then don't. Listen to what your body is telling you.
So, thanks, Dr Adams. And, thank you coach for getting me off my ass, and exercising again. Energy level? I highly anticipate your return. :) Here's looking forward to the 2011 season. May you be fast, and exciting, and even better than this past season.
