My wife and I took one full dropper, which was a huge mistake! By 2 hours plus, we were done for! My wife felt like she drank and had a hangover, I felt so gone like I smoke a whole cannabis joint by myself! And I’m a light weight! Lol I love it though, my wife said never again!... Also, for my tolerance, I took only 15 drops under tongue the second night 2 hours before bed, and it was just right, kinda felt the body buzz the next morning, but nothing some coffee won’t melt away! Will definitely...
