Sleep troubles

For awhile now I’ve been struggling with sleep. Not being able to sleep or having trouble sleeping, And even if I sleep A full night I still feel like I haven’t slept in years.

For the night when I know I won’t fall asleep I take a melatonin supplement but some nights that doesn’t even work. I was wondering what other things are out there to help me. And maybe one of them will help me get a full nights sleep and actually feel rested . What other things ate out there?
