He hasn't been so good in Houston. He had an arm episode, and had to take his medicine for that (he hadn't needed that in about 3 weeks). His arm was shaking too bad to sign in at the doctor, and he couldn't walk far without limping or being winded. He tripped and fell on the plane. He seemed to be doing well at home...it looks like either flying or going to the doctor in Houston doesn't sit well with him. Sherri thinks it is lack of sleep. He did admit that he gets nervous before these trips and doesn't sleep very well.
