Is there a neck pillow that can help me sleep at night?

I can’t really fall asleep so I was thinking about getting a new pilow. I was thinking about a memory foam pillow or something like that. Does anyone know of one that might help me sleep. My neck does sometimes hurt but not even close enough to make me not want to go to sleep. Does anyone know one a pillow that might help me sleep? and I usually drink water so caffenine is not an issue.
