That is great advice, BB!
I'm fortunate in that I work at home. I go to sleep when I'm sleepy and I sleep until I wake up naturally. So I have a very good relationship with sleep. I rarely have to force myself to go to bed at a certain time, or fall asleep at a certain time, for outside reasons.
For me, going to bed at the same time wouldn't work, because I'm not sleepy at the same time every night. Some nights I'm sleepy early and go to sleep early. Other nights I'm full of energy and stay up longer. Maybe my body is odd
