Makes ALL the difference in the world for my husband. I've known him for 15 years. The first 13 years he had HORRIBLE sleep issues....and tried EVERYTHING and I do mean EVERYTHING. The last two years (since we've begun growing our own) a ganja cookie a night does him great. And like M fellow said.....it's the difference between 3-4 hours of crappy rest and 8 hours of good sleep. He's definitely much happier and healthier for it.
