Here's last nights data (with oximeter imported):

More is definitely not better. I'd start with 0.3mg melatonin and then increase that up to 1mg at most. I'd also consider some lifestyle interventions to naturally increase your melatonin production and be more tired at night. For example exercise, no blue or bright lights 1-2 hours before bed, not eating 3 hours before bed to see if you can be more naturally tired.

My subjective experience with too much melatonin is that i'd wake up in the middle of the night and i'd be excited and happy. I'm not a doctor FYI so take this with a grain of salt. Serotonin is a precursor for melatonin, which means serotonin is used to create melatonin in the body. In these types of interactions it is possible that supplementing melatonin can increase your serotonin as your body doesn't need to create it's own. Which seems to align with what i've experienced.

Looking at both nights, despite the reported low AHI number on your nasal night, the O2 desaturations remained high - 15.2 per hour.  There should not be that much difference between your AHI and ODI.  Your ODI was still high on the comfortable night with the FFM.  If those numbers are accurate, it's a bit mystifying.  You may want to check back with a sleep clinic for an explanation if you confirm that your pulse oximeter is reporting accurately.   In the Viatom app dashboard there is a perfusion index number.  It should be above .4%.  If it isn't, you won't be getting accurate O2 readings.  

Personally, if I had to choose between groggy/fatigue and worsening TMJ, there would be no contest.  I'd go for groggy.  Having pain every time you chew, not being able to open your mouth all the way, have a jaw lock open or closed, eating only soft foods - for months - is depressing - though it's great for weight control.
