That's irrefutable by design. It _could_ lead to all those things. But it could also _not_ lead to them. Depends on the person. Besides, it's not like people with obstructive sleep apnea are having great sleep to begin with. FWIW I have facial hair so I did not use the tape. For me merely breathing through my nose during the day turned out to be sufficient to be able to comfortably do so at night.
