No, she doesnt fall asleep at the wheel. Never has. As for the therapy... that sounds good in theory, but would be incredibly difficult to apply. There is no routine to her falling asleep... one night it could be 8:30 the next, could be 10:30... just the other night she was joking around with me and singing product jingles one minute... and then I look over at her and BAM... lights out. She spent that night on the couch until 11:30. The night before that... she was out at about 9:30. On the couch til 3am or so...
The therapy sounds good, but you need to be willing. I dont think she would.
