I can't sleep

It's early Wednesday morning, and I can't seem to fall asleep. My dad is supposed to be released from the hospital today. He still has all the outward signs of the Syndrome, but the doctors say he's recovering nicely and has been flirting incessantly with the nurses. I am a bit reluctant to see him getting out before he's completely cured. After all, I think he was prematurely released after the surgery on May 5th, indirectly causing the syndrome in the first place. When I see him in person, he seems to be getting stronger, though he still looks terrible. And when I speak to him on the phone, he sounds so weak and frail. I don't think he's got that many miraculous recoveries left in him, so I don't want to push his luck.
