I was disappointed in how badly worded a few of the questions were presented. One relatively early on asked about an either/or situation, but the choice of answers was yes or no. Neither answer made sense. Other questions were worded as if you had just started with sleep apnea, but made no sense to someone like me who has been successfully using a CPAP machine for 20 years. It would have been better to ask about current treatment/machines early on in the survey and then aimed appropriate questions with that knowledge. I hope you can correct these flaws and look over the questions better for future users.
