I think you may be reading this wrong, I have like many other CPAP/APAP users had day sweats, anxiety, depression etc, all due to missing nights on the machine, it could be that you are suffering from these anxiety issues as above.
For example, if you miss more than 2/3 nights on machine you will go back to square one with your treatment, missing 2/3 nights then going back on the machine for one night will not help you.
You must use your machine every night, then your day sweats will cease,
You may not be using your machine for various reasons that you do not state, like mask leakage, feeling claustrophobia, have trouble with inhaling or exhaling, you are not alone with these issues with none use, it happens a lot, we have all been there at one time or another,
Read again what KimR says and do that if you do not want to listen to what advise I can give you, he also says “HORMONES”, you do not state your age, so I am thinking is this just the menopause?
