Try it sometime, I think this one actually works.
Prayer for Sleep
I am heavy. I am heavy.
My hands and feet are lead.
I am sluggish. I am languid.
I cannot raise my head.
Air flows like syrup.
Air sinks to my feet.
Air makes me languid.
I am complete.
Dream of sinking, dark and deep.
Slow and soft. Dream of sleep.
Dream, sleep.
Exhale.
