I have a CD player and I've got some quiet music that I'll listen to....it relaxes me and I'm asleep long before the CD is over. I try to stay away from music that has words because I find myself "singing" along and that defeats the purpose of the music.
Some CDs that I have used are: Jim Brickman ( he's got a lot of music & usually has only one or two songs with words), a CD with a collection of lullaby songs, classical music (I've got a CD that's got a Beethoven Piano Concerto that I heard while at a concert of The Cleveland Orchestra) I listen to this quite regularly. Buy a CD of quiet jazz music or other background music. For me, this works pretty well.
Sometimes, for the short term (up to two weeks) I've used some pills to help me sleep. One over the counter medicine that works is diphenhydramine (50mgs). Diphenhydramine is the same ingredient as Benadryl. So you can get the Target equivalent of Benadryl. Target also has a "nighttime sleep aid" which is where the sleep stuff is, but it is cheaper to use the Target Benadryl.
The Niquil-ZZZZZ stuff is also the diphenhydramine...but it's a lot more expensive because you're buying the brand. If you're unsure of using a sleep aid, talk with your store pharmacist and the pharmacist will help you.
One other thing that I do is kind of like "counting sheep" I'll lay on my back and take deep breaths...concentrating only on breathing.....but count each time you exhale. For me, I'm usually asleep before I hit 75 exhales. If my mind wanders I'll make myself start to count all over again.
Sure do hope that some of these ideas might work for you.
If sleep remains difficult, try some relaxation techniques...or, see your doctor if you have one.
