One thing I have learned is: sleep is not some separate category of life, treatable effectively with magic potions, and eyeshades.
What are your waking hours like? Do you do go all-out in ways that usually produce mammals in need of sleep?
If not, why not? Go for it. Go to bed exhausted from your true passions.
If you insist, stay find yourself awake. If that's your choice, don't make it worse with worry. I sometimes can't sleep, and when that's the case, I make a point not to add mental agitation, which is a form of work, and quite demanding. I breathe. And at some point, I wake up.
When I do, it's light outHaving slipped into sleep at some point. OK?
