My gp referred me to a sleep study clinic at the university hospital. I answered a questionnaire, like do i fall asleep at stoplights while driving (!). Then they looked in my nose, and scheduled me for a sleepover. The sleepover was from about 7 pm to 6 am. They take a few hours to glue sensors to you. It might be awkward with your dog at that point? Idk.

My insurance paid for most of it, idk what it cost.
