Have you tried taking a melatonin supplement? I can have a really hard time sleeping, my mind races as well. It's hard for me to wind down after being busy all day. There's a really good melatonin supplement at Dollar Tree by Nature Garden. They are tiny chewables that not only have melatonin, but also: lavender, chamomile, and lemon balm. They help give you that extra push into sleep. I love them, and so do others in my family. I'm really so glad I tried them. They're natural and not habit forming. They're labeled as a sleep aid, and they actually taste pretty good. You get 8 in a box for $1, it definitely couldn't hurt to try!
