Like Shelley said, the anesthesia used in surgery can often have some strange and lasting effect. I had outpatient surgery on a tuesday year-befor-last. I remember being on the table, then I remember being at home that night, lying on the couch and trying to talk to a friend who had come to visit. But the next thing I remember was walking downstairs on Saturday. I actually lit into my kids for skipping school, since I thought it was Wednesday. For weeks after the operation I had problems with my digestive tract, and lost a lot of weight. I was clumsy and slow to respond, and I couldn't concentrate much at all.

I'm not saying that this is what's wrong with your friend, but it is worth considering. I hope you find the answer very soon, and your friend returns to normal. It's very kind of you to care so much about her. Good luck and God bless you and her both.
