I had quite a persistent habit of laying on my bed because of lethargy, but afterwards I find myself locked to my bed unable to perform any task which I always found limiting and frustrating.
I have made a change to this by setting a setting 'opening hours' for my bed. My desk is only open from this to that hour and my bed is only open for this and that hour. And it honestly helps a lot, it helps with energy during the day, I find myself doing more tasks easily because I am already at my desk and I find myself falling asleep quicker when I do get into bed.
