Wow, Didnt realize I would create a debate. This is just an update. I received my bottle about an hour ago in the mail. This is my review of the stuff. I am using a newly opened resurrector cartomizer, with a fresh charged Riva . First off the taste. It taste much like an herbal green tea with a wedge of lemon. I find it very pleasant and I could use it as an all day vape. The TH is light. The vapor production is good, but not great like a higher % VG based juice. Now that is out the way, whether or not it may help one fall asleep. I have been vaping it for about 30 min moderately, with a few puffs every min or so. I do not feel "sleepy", however I do feel more relaxed. I feel like if I were to vape it if I was tired to start with, that it could possibly help me fall asleep. I am going to vape it for the rest of the night and see how it goes. To the people who said it might just be a placebo effect. This might be true, because I read and did the research and I believe in the use of herbs that have been used for 100's to 1000's of years have some validity to them, and I want it to work. I have no way of doing a blind control test to see if it is all in my head. This being said, even if it is just a placebo effect, if it helps me sleep, then I am happy.
