4 doesn't seem to be a real thing because the only gene therapy for sleep that I could find were trials centered around GT for sleep apnea.

Listing gene therapy like you can just go to the doctor and request it is pretty disingenuous since insurance companies will make you jump through 10,000 hoops before even attempting something as expensive as gene therapy.

5 is a sleep apnea thing. i snore (very lightly unless i'm congested) but don't have sleep apnea. snoring can be an indicator, but there's not a 1:1 correlation
