@willsecurity usually you need to do a sleep study (you go somewhere one night, they hook you up to a bunch of machines, you go to sleep, and they monitor you while you sleep).
@willsecurity you could probably do it at home. likely the most important bit would be an oximeter to see if your breathing is stopping.
@H3athers What if .. for example you are an insomniac that can't sleep in strange places ?
