Yes, i recently remembered that computer/phone screens block your brains ability to produce melatonin. that's one sleep hygiene thing i'm bad at, so I'll work towards improving.
I had 2 sleep studies at different times and don't qualify for the diagnosis, but the data showed I never go into deep sleep. I only sleep in stages 1 and 2, not 3 and 4. It impairs hormones, your body's ability to repair, store memories, etc. No wonder I feel like crap. The sleep doctors are clueless about this and don't treat this, and it's not even a diagnosis. Rheumatology articles look at this issue in fibromyalgia, which makes me wonder if lack of restorative sleep is really the cause of fibromylagia.
As ambivalent as i was about it, I just ordered a bunch of supplements. Low vitamin D3 can make sleep disruptive and my levels are really low. I got magnesium glycinate and am going to try to use that as a replacement for ambien. There is a lot out there on that supplement being good for insomnia, sleep quality, increased melatonin, example:

I've been meaning to do those relaxation exercises-do you have a youtube link to a good one?
