Immunity?

I had my first food dream last night, and in it I was really hungry. I haven't lost more than a few ounces the last few days, so I'm thinking that I may be building up an immunity to the hcg. I've also had a screaming headache the last few days...not sure if it's connected, or a coincidence. But I have needed naps and I am exhausted and achy. I'm trying to drink more fluids, hoping that will help.
I really don't have much else to talk about...sorry I'm boring today. I will do better when my headache is gone. Tootles!
