I hope so too - alcohol is slandered for causing sedation rather than true high quality sleep, but the research is still uncertain about marijuana.
I've tried zinc, magnesium, melatonin, sleep masks, earplugs - many things. Cannabis is the only thing that works.
>I'm not really sure if I was happier, or more productive, I was definitely more relaxed, it was probably the pot not the sleep.
I'm inclined to believe that sleep is the key here and pot helps by inducing it. That's my gut feeling though.
