Sorry for the delay in responding, SpecialPrincess
I was busier than expected this weekend.
It's really one theory in two stages. Work up to all 4 basic food groups, then work up to all 4 organic food groups. This appears to work if you are experiencing tired/exhausted during the day. As night approaches they'll become tired and then later tired/exhausted.
So, I've had to switch day to night this morning.
