You need to ride harder so you get more tired and go to sleep earlier. I used to have sleep problems. I would stay up hours past my wife and wake up at the same time. Now I am the one begging her to go to bed so we can get to sleep. I used to contemplate sleeping at 1am to wake up at 6:30am. Now I am in bed around 10pm for the same wake up time.

That has probably been the biggest change I noticed now that I ride a lot.
