Dear Karen,
Routine bedtime, a bit of carbs snack before bed, darkness, being warm, white noise and/or earphones and gentle music are a few of the things that work for me. I can't take sleeping meds because I have a history of sleep walking. Key for me is not being awakened once I get to sleep. I use music and earphones, but white noise of a fan works too, just not blowing on me. I make a plan of things to do when I do get awakened that will eventually make me drowsy again. But I do not leave the dark room or move my body as it needs the rest. But even bumping my feet together will do the waking up. Having things within reach so I don't have to move my body has worked best for me though. My feet and legs need to be up(I sleep in a recliner to keep myself from turning over and bumping my ankles together) for at least 8 hours.

It took me a long time to develop a plan that works for me, and it doesn't always work, but I've stopped panicking about it. But I don't work now so the pressure is less.

Hope this helps a bit.
