What is the best way to get the best quality sleep? 15, male obviously still in puberty and I would really love to get up without a half-dead drag...

I'm following a low carb diet (<60) as of today, what else should I do before sleeping?

The diet will Be mainly grass-fed beef, organic eggs, whole milk, occasional salmon, dark green vegetables, POSSIBLY a nice nutritious fruit post-workout.

My workouts are 3 days of sprints and weight training if that helps. I know at least 8+ hours of sleep, but how can I wake up with ease instead of with a drag?

Some good, sound advice is much appreciated. Would a completely dark room help( besides alarm clock)?
