Sleep study???

Su

I was wondering if anybody has gotten a sleep study done. My husband has a terrible time sleeping and it makes me really worried about him. Often times he only gets about 2 hours a night and then his body wakes up and won't sleep no matter how tired he is. We don't have insurance right now so I need to know how much it costs. Maybe we can save up for one. Im so worried for him. It can't be healthy or good for him at all.
