It's been this way for nigh on four years now, ever since I had a really bad flu-like illness in late 2003. My energy has gradually run down, my temper's gotten shorter, I feel more stupid, and I fixate on things that shouldn't annoy any reasonable person. (What's really bad is when you know things are wrong with you and not a whit what to do to change it. It's like being aware of Alzheimer's or something.) Thanks for the support.
