These drinks work, to a certain extent. If youre expecting some intense buzz from something you can buy from your local corner store, try some spice (just kidding, dont touch that shit youll die, buddy's neighbors were addicted to the shit because they were on papers and ambulances would come on a regular basis because the dumbasses were having seizures). It will relax you a little, and in my opinion make you tired. They aren't really worth the money unless you also enjoy the taste, I love the citrus ones that come in a can ( I dont think these are the same as the bottles).
