Sleep training, if you have the ability to control your schedule.
Develop a schedule to be asleep. I have a pre-sleep sort of ritual/schedule that begins at about 10:30 and ends drifting off into sleep at 11:30. Lights out, turn down the TV, a little snack (I get hungry when I sleep?), turn down the temperature, a little diaphragmatic breathing, etc. and by the time the news is over my eyes are closing.
It takes time and consistency, but once ingrained its a pretty durable habit.
