Love usleep!
I use both urelax and usleep. I love them both! I think usleep is the more effective of the two - it brings on sleepiness when I need it to and I don't wake up feeling tired/hungover like I do with melatonin. I started using these after I kicked my nightly wine habit, and I look forward to them each night bec they are so delicious :) I don't think either of them would help you quit drinking if that is your end goal, though. Reduce, maybe! There is a warning about kava regarding your liver, so that's something to ponder before making a purchase.
