What"s a medication that can truly knock you out?

I have mild difficulty falling asleep. I sleep like 10 hours a day.

But I likely have a sleep disorder, and I wake up like I never slept in my life.

I want something that kicks me into a coma. I want to be knocked unconscious to feel, for once, like I have truly slept.

Is there such a thing 😭 I figured you'd be the best people to ask. If this doesnt make sense, please have some mercy I'm tired
