Marley mellow moods. Trust me! 2 bottles 10 hour coma.

You're thinking of trptophan, which is eventually metabolized into melatonin. Melatonin is what is common sold in drug stores as a sleep aid.

So much this. Getting away from the bright screens of tv, laptops, tablets, and cell phones a fair amount of time before bed will do wonders.

“Artificial light exposure between dusk and the time we go to bed at night suppresses release of the sleep-promoting hormone melatonin, enhances alertness and shifts circadian rhythms to a later hour—making it more difficult to fall asleep,” says Charles Czeisler, PhD, MD, Harvard Medical School and Brigham and Women’s Hospital. “This study reveals that light-emitting screens are in heavy use within the pivotal hour before sleep. Invasion of such alerting technologies into the bedroom may contribute to the high proportion of respondents who reported that they routinely get less sleep than they need.”
