No., not directly. This a drug used for insomnia, jet lag and possible REM sleep behavior disorder. This can be used to help patient's struggling to use CPAP initially fall asleep. It is non addictive and an effective sleep aid.
Melatonin may help you to fall asleep but it only lasts in your system for a couple of hours so it rarely helps to keep you asleep. It should not make much difference in how effective it is if you do or don't have sleep apnea. As you are using your CPAP, then you are more like a person who does not have sleep apnea. If you choose to use melatonin I would recommend you not take over 3-5 mg at bedtime. If you sleep better taking melatonin I would keep taking it. Some persons alternate sleep aides to avoid building up a tolerance. Your dry mouth suggests you may be losing air through your mouth. A chin strap or a full face mask may help. There are over the counter mouth washes which are specific for dry mouth and some persons find relief by biting into a Vitamin E capsule and swishing the contents around in their mouth then swallowing the gelatin lining. It will line your mouth for awhile.
