Any home remedy or cures for insomnia?

Here lately it doesn't seem to matter what time I goto bed I wake up somewhere between 1-3am. Like earlier I fell asleep between 11-11:30 and was awake again by 1am. Does anyone have a drug free remedy that will help me sleep soundly during the nite. I usually end up falling asleep again around 5-6 am. But this is really wearing me out. Im not sleeping straight through the nite and when I wake up im up for a while.
