I am 61 years old and can count on 1 hand the number of nights that I have slept all night and felt refreshed the next day. I have tried everything out there. Melatonin does nothing. Prescribed drugs either don't work at all or give me horrific nightmares! I have tried calming herbal teas, OTC medicine, yoga for sleep, calming sleep apps, black out curtains, did a sleep study (which resulted in no sleep apnea but no other answers either), a sleep schedule, eating protein before I go to bed or later in the night. Nothing works and my brain never shuts up. When I was in college, I would lay awake and write my papers in my head. Having hypothyroidism, celiac disease, great stress and anxiety ( I am a special education teacher and caregiver for my husband) does not help. I have learned that praying myself to sleep is the only thing that works. Not sleeping is frustrating and then I feel sluggish and get migraines!
Good luck to y'all!
