CATScan came back clean, and they have ruled epilepsy out. Praise God! The drs are leaning toward stress and lack of sleep. Nathan has had problems sleeping for about 6 months or more. He is being released to go home and all his tests will be sent to a neurologist. I'm hoping they get a second opinion just to be on the safe side. He will be unable to drive for 90 days. That will be tough for a senior in high school! Thank you all for your prayers! This could have been so much worse.
