I don't think it ever really goes away completing. Just comes and go at any time. This sounds stupid but sometimes when I am feeling like this if I drink a glass of water and eat something it starts to go away. It might have something to do with stress and blood sugar drop combination. But I no doctor....

I have a similiar feeling. It's like I have a perma-hangover. Also have numbness in my head. I went to the dr and he thought it was stress related. No tests or anythign. I tend to agree that its stress as I have been pretty stressed lately. Its scary though because I wonder if I have a brain tumor, ms, whatever....
