melatonin worsens my sleep apnea! it relaxed the throat and prevents breathing in some

Your issues are more than likely caused by mask leaks waking you up from REM sleep because your lower jaw is dropping. Try using a chinstrap or mouth taping depending if you are using a nasal vs full mask. If using a full face mask use a chinstrap or cervicsl collar. If using a nasal mask use mouth taping, cervical collar, or chin strap. You can also analyze your data with a program called OSCAR, it will show you your leaks and you can probably correlate the awakenings with leaks or possibly legit events.

Melatonin worsened mine and I woke up with a blazing headache and it felt like my eyes would pop out of my head. Good luck.
