I've tried the take home mask, and it was very uncomfortable to sleep with. I did wake up once in a way I normally don't, so I felt the study was invalid at that point. Surely the technology has changed in 5 years, but for light sleepers like myself, sleep studies with equipment attached to your body don't feel like fair trials. MRI sleep studies can be an option, and if I had to do it again I think that would be optimal for me.
