Devon has mono. Never doubt your mommy instincts. His blood sugar was also a little high - 124. They asked if he had been fasting, and although I can't be sure (he's at work), I don't think he ate anything yesterday before the test. He had slept all day and made it to school in time for last period, came home and then had the blood work done. Still, I want to pursue more testing for this since he's been sick so much. He's gotten so thin. I'm adding vitamins and more supplements to his regimen and am going to bring him healthy snacks when he's in his room playing Rock Band. But, I am worried about him. He looks sick. And he has for some time. I have little doubt that his mood swings are a direct result of his health. Please keep a good thought for my boy.
