Anyone else experienced this? I'm usually a red day person but this week I've decided to go green for the whole week to see what happens. I'm not even having meat in the healthy extras, just cereal or bread. For some reason I seem to be more tired than usual. Work is busy as always and I'm sleeping about the same hours and doing roughly the same amount of walking (2 miles a day uphill!). Should I be trying to have a little protein or am I just having a sleepy week?
