Hi! Today is my second day on Kay Sheppards plan. And I feel terrible! I'm not hungry, I don't have any serious cravings, I just have this terrible terrible headache, that is very persistent, aspirin and paracetamol resistent

I also feel drained, no energy at all. I'm fine when I get up but after three or four hours, I feel so sleepy, no energy whatsoever.
Tomorrow I need to go back to work, and I only pray that day three will be a bit better.
I do think, that all this is due to caffeinne I'm not having...
