Are you ruminating in bed when you are trying to fall asleep? That's when it tends to get me. I have a few distractions, some of which you can do at any time. But I do these at night in bed since that's when I ruminate. I distract myself by fantasizing/daydreaming. I've come up with many trashy romance novels in my mind at night. ;-) That takes some creativity, though. If you're not the creative type, some bold visual imagery can also be distracting. I think of soothing things. For example, I will imagine that tiny Buddhist monks are washing the inside of my head, clearing all of my worrisome thoughts away. I picture them with soft cloths wiping my brain of all the worry and replacing it with peace. I know that sounds odd, but the vivid imagery pulls your attention away from those thoughts. If you just count sheep it won't work because it's boring. It has to be something unique to draw your attention away. The last thing I do is I sleep with a soft Snoopy. I use it for a tactile distraction, focusing on his soft little ears or nose or paws and it helps me feel comforted so the negative thoughts don't have so much power.
