Shove my husband and tell him to stop snoring.

I pay attention to my feet and feel that they are asleep, then my calves, and so on until I feel like my whole body is asleep.

Count backwards from 100 in Spanish in my head, or think about slowly descending through the color wheel from a bright loud red then orange, down through yellow, to green, blue, sleepy deep purple.

Also - don't get in bed until you are sleepy. Exercise during the day. Yin Yoga before bed.
