I'm trying to follow that protocol. I don't expect to ever be able to exercise and be conditioned like I was before given that I ran two days after the hit to my head (because I thought I was groggy from the long weekend and just needed to sweat it out unaware of my head hit). I also lifted weights a lot and went trap shooting within the first two weeks unaware of my condition, so I am sure that it will be a long time before this stuff settles out given how much I exerted myself so soon.
