Lewanda, out of curiosity, have you ever tried "just" the vitamins? Whenever I've tried just them (cause I didn't have any fruit) it seemed to make no difference.

Oh, but to the person who posted this question -- I agree with everyone here and they are all great ideas, but I also think that you should try to get a doctor's consult as it definitely may be something more serious. I had two that have had that happen and one of them was almost dead before I got the consult. Course, that was within the first 24 hours of getting the game and I was still trying to learn it, but it does seem as though persistent weakness problems is a warning sign of a more serious disease.
