What is this feeling? Can you describe?

You can't focus--you can't concentrate, but not in an agitated way. You feel dull, like a block of wood.

An old Anglo-Aussie colloquialism comes to mind [forgive the pun]:

'woozy'.

Gilmer was more precise :-)

The best way that I can describe it is how your head feels when you have the flu or a cold. Your head just feels full. Not in a weight sort of way but like you can't quite think very clearly. Almost like the feeling you get when you're exhausted.
