How to participate in a sleep study
It made me
have to do it again 
"The started the damn study at 10pm, when I go to sleep at 3am!"
How I did it: Make sure you get them to agree to start the sleep study when you
usually go to sleep, especially if you're a night owl.
In my
case, I used to go to sleep at 3am, the study started at 10, so I only
got 3 hours of sleep analyzed.
