Hi K.,
I am sorry that you are unable to sleep.:( That is miserable!
This mostly happens for me when I am away from home, so I use this to help my body and mind relax...
I hope that you find it helpful. These are just a few that come off of Youtube.

Let me know if the link does not work in your area, and I will try to direct you to finding other Binaural Beats/Soundwave Therapy to download.
Best wishes!
