Go to sleep sober after a good days work and physical activity. Be straight.
You will jump out of bed in the AM.
Use drugs, alcohol, weed, etc., to get to sleep, you will wake up groggy and need something else to get you going.
Natural quality sleep doesn't come from Ambien or other "sleep" drugs, so you don't get natty REM. Just like natural muscle doesnt come from juicy juice.
