Well, it seems that my theory about my Hebrew textbook causing problems has some merit. I did not have the class Tuesday, and I felt fine. I did not have the class today, and made it to all my classes (didn't feel fine because I started feeling ill halfway through my last class, but the only pain problem is my knee).
I'm going to make photocopies of the next couple of chapters and carry those to class tomorrow. It *should* make things better than they have been.
I'm also going to continue taking Tylenol all day instead of after I start hurting, since that was the other factor today, and it seems to have helped.
I also talked to my boss today about what he needs from me in order for me to stay on track. He suggested that I do some program planning now, and set five dates, and then I'll have some preliminary work done. I think I'm going to do that this weekend.
