So tired

Well, I'm eating carbs again. And my energy has improved somewhat. But I'm still bloody tired. Keep falling asleep after a couple of hours of activity - not even that much activity, mind. Today I went to the shopping centre and got my nails done, and then came home and had a nap. I have a very full week ahead, with work and then going to Canberra so I'm still quite concerned. I don't know what to do.
