Do you have…

Step 1: ….difficulties falling asleep, staying asleep or waking up too early?
Step 2: ….breathing difficulties during the night, such as snoring?
Step 3: Are you 18 years or older?

If you meet all three of these basic criteria, you can complete our online screening questionnaire. This will allow us to determine if you are eligible to continue to the next two stages of screening: a face-to-face interview and one overnight sleep evaluation.
