You must go to bed at 6pm. A little early for me.
This time of the year I'm up by 6:30 because its hot and my golf group plays early to beat the heat. Winter time I sleep to 7:30 or so.
Good thought about not watching TV in the morning; it just isn't a good way to start the day. Music or silence is much better.
we are the opposite, i am in bed at 9 or 10 up at 5'ish....with in bed around midnight up at 8'ish....Wife goes to bed 9-10 and is up by 6. I go to bed around midnight and up by 8 (sometimes 7).
To bed around 11, wake at 1:30 & go back to sleep around 4:30. Wake again anywhere between 6:30 or 8:25. The latter is an alarm. I don’t let myself sleep any later than this. Whenever I manage 7.5 to 8 hours I feel wonderful.
The only good thing about winter is the dark mornings. It’s easier for sleeping.
Have you tried wearing a sleepmask? I wear one every night so light doesn't affect my sleep. I'm irritable if I don't get enough sleep.
