I've had pretty good energy though not as much as yesterday. I did take a nap this afternoon, but those don't have to indicate a lack of energy.
My mood has been good today and my thoughts clear.
The cravings are now completely mental. Given all the advertising and my past lifestyle, I don't think I could maintain Whole 30 or even Paleo 100% of the time, but I have done a good job resetting my blood sugar so eating crap is now a conscious choice rather than a necessity.
