My head has been feeling funnier than usual for the past week. It's not a new pain or anything, it's just uncomfortable. I feel impaired...not the same feeling as being drunk, but somewhat similar? I'm not having any difficulty concentrating...that would be terrible, I'd lose my job real quick! But I am having trouble finding words and when it gets real bad I can't remember what was said to me 30 seconds ago. Is this what you call "brain fog?" What does it feel like for the rest of you?
