I do too. I was skeptical about trying this, but it does work sometimes. Anything that helps, even once and a while, is better than nothing.
I start with my toes and say
"my toes are feeling warm and heavy, my body is relaxing so I can sleep"
I work my way up my body, legs, abdomen, lower back, hands, arms, chest, upper back, neck, jaw, and head.
The first few times were awkward, but after a few nights of trying it REALLY helped. Even if I don't fall to sleep my body always feels better after.
Good luck
