Sounds like you off to a good start! If I was in your shoes I would change my going to bed time by small increments and keep the wake up time at 8:00 for a while (constancy is important don’t make more than one change at a time). If last night you weren’t able to fall asleep until 2:00, maybe try going to bed at 1:30 and keep your goal at a wake up time of 8:00. If you are able to fall asleep within a reasonable amount of time keep incrementally making your bed time earlier. Your doc probably already told you this, but if ideally if you wake during the night and can’t fall back asleep within 30ish minutes leave your bed. I’ve found moving to the recliner in the living room and sipping a cup of herbal tea while listening to soothing music can be helpful. Also be sure to remove visible clocks from your bedroom.Revived1 wrote: ↑Fri Jul 03, 2020 3:21 amJust an update on how I went using the light this morning. I used it on blue light mode for half an hour. I was pretty tired, because I had only slept for four hours (a habit I seem to be in, lately), from about 2am to 6am, and been awake from that point on, even though I was still tired. My aim is to get up at 8am each day, so I waited until 8 to use the light. I don't think I've noticed any real difference so far, although any benefit will hopefully be seen in that maybe I'll go to sleep earlier tonight or wake up earlier tomorrow....well, not earlier than 6, but earlier than 8, maybe. I'll see how it goes. I think it's going to be a big help in the long run, though. My sleeping habits have so many issues that I'll have to get everything organised, and it will take time to do that, but I think the light will be a big part of getting my problem fixed.
My son was prescribed light therapy for a circadian rhythm disorder (he also has OSA), he didn’t feel better after a single night of light therapy but improvement was surprisingly fast. He also followed all the other doctors recommendations, which likely hastened his improvement. As horrible as it sounds for most of my son’s life I would have to resort to dramatic measures like dumping cold water on his head to wake him up so he could make it to school in the morning

After light therapy combined with treating his OSA and a strict adherence to other recommendations by his doc, my son has actually woken up on his own naturaly at 7:00 for the last couple of years

Your sleep doctor is a keeper, many sleep docs are singularly focused on OSA and miss other sleep disorders.
Good luck to you, I hope the combination of light therapy and treating you sleep apnea will lead you to a restful nights sleep!
