I didn't get the "headband" effect, which is great. The high really creeps up on you. It feels like it's not very strong at first, but give it several minutes and you'll suddenly find yourself with a big grin on your face. :)
This is pretty strong stuff. Don't try this if you're planning on doing any other activities because it'll hit you hard and you'll be stuck on your sofa for the rest of the night.
This was really good- I can be very productive with this, or just be lazy and watch Netflix all night- the only really bad thing though is the cotton mouth- I feel like I have to brush my teeth every hour when I'm having this- well worth it though (and it's good to brush your teeth often anyway).
