Out of curiosity, did you have any luck at all with the glasses-style light therapy devices like the Luminette? I was having limited success with other forms of light therapy (and the rest of the laundry list of interventions), and some recommendations from an experimental non24 protocol (https://circadiaware.github.io/VLiDACMel-entrainment-therapy...) lead me to finally try the glasses type and it's oddly effective, so far. I'm waking up around 10:30 AM without alarms and without sliding, which has... literally never happened before. I'm just hoping it won't regress to the mean after another month.
