Try drinking some warm milk before going to bed. Sometimes people can get to sleep by drinking some warm milk.
It's like a natural sedative.
Avoid caffeine around 3 hours before bed and avoid electronics about an hour before bed.
The light from electronic screens messes with our bodies internal clock.
Try staring at the ceiling for awhile. I find staring at the ceiling puts me to sleep very quickly.
If all else fails you might have to resort to taking a sleeping pill. I hate taking sleeping pills but even sometimes I have to resort to them otherwise I'd be too dang tired and not alert during the day.
