It most likely has nothing to do with your specific product. I've tried Tylenol PM, Nyquil, and Simply Sleep before, and I had basically the same effect with all of them, but your product definitely knocked me the fuck out the fastest. I'm not a big pill/medicine person, so my body probably handles things differently than most people. I took one of my mom's xanax's once about a year ago when I was really upset when I had to put my dog to sleep (had him from 7 weeks old to 9 years old), and I'd say your sleep pills gave me a similar effect. I could probably bag these things up and sell them as an RX pill to college kids, lol. It definitely does what it's advertised to do!
