This was my first time trying CBD oil. It has a very subtle, relaxing effect. I'd say it's roughly on par with a cup of chamomile tea. I've tried it for about 10 days so far, taking half a dropper at night and a full dropper in the morning. It seems to improve my sleep at night and calm me down just a bit during the day. The CannaTech CBD is pretty expensive (hence the 4 stars, rather than 5), but the price is comparable to other brands. I'll order it again, just to see how it works when taken a little longer. The taste is also very mild, and I'm fine with it. The shipping was also insanely fast. I received it the next day.
