Adult with hyposensitivity(?) and sleep problems
I'll tell you what I've done that's mostly worked.
Ear plugs (I think the pressure in my ears helps)
Melatonin or Unisom (trazodone worked well also)
2000 ui Vitamin D with breakfast
High dose of magnesium with dinner
Eating something right before bed
A massage of any kind from my husband (firm hair stroking or a foot rub have had the best results)
Long, hot shower
I still expect to wake up for about 1.5 hours around 2:30 am. Planning for it, embracing it, and enjoying it help me get back to sleep eventually. And a 3 am snack helps too, some kind of bread with a lot of butter on it.
Hopefully that helps someone out there.
