Sleep hygiene.: To reset your sleep clock, go to bed at the same time every night, awaken at the same time every morning, don't nap during the day, use the bed for sleeping (not eating, TV watching, reading, etc), if you awaken during the night, stay in bed until your determined awakening time. And certainly don't drink caffeinated beverages within several hours of going to bed.
