Have you tried meditation music with psalms, have a look at youtube for this mix, it helped me at a time of sleep deprivation?
Proverbs 3:24 King James Version (KJV)
24 When thou liest down, thou shalt not be afraid: yea, thou shalt lie down, and thy sleep shall be sweet.
I enter into the perfect rest of the Lord. I claim my healing for Insomnia. Thank you for that perfect sleep, Lord! I am a new creation in Christ! I am lead by the Holy Spirit! I claim the perfect love of Christ! I cover my mind, body, and spirit with the blood of Jesus, and loose angels to stand guard and to protect me while I sleep, in Jesus name. Thank You, Jesus.
