I have a really hard time with sleeping. Unmedicated I have vivid nightmares everynight, and struggled to sleep with the voice talking nonstop. I still struggle to get to sleep. Listening to news helps some, especially stations like fox that repeat the same loop every half hour in the night. My dad uses this too. When he wakes up it's a little less freaky when there is this constant drone of news to help orient you to your surroundings. I usually take a sleeping pill once a week or two to catch up on sleep or a couple benadryl.
Wishing you the best of luck.
