How Do You Feel on Waking?

Clarification: I don't actually experiences nausea, I experience terror. Sorry.

I was watching a trailer for a new documentary called BRIEF ENCOUNTERS. The film maker said he woke every morning feeling sick at his stomach. I have never heard anyone else say this, but I wake every morning feeling sick at my stomach. It's not stomach related--it's non-specific fear, I think. It is not based on bad events ahead or behind me. No matter how great the day might be, I awake feeling sick at my stomach. It disappears after a bit.I've been up fifteen minutes as I type this and it is mostly gone.

I have been told it is a brain chemistry thing but I wonder how common it is.
