As soon as it arrived i had some in water didnt notice any buzz of energy but i slept thru the nite which is a big deal for me the next few days i was not as tired during the day and i drank more water another big deal i love it i feel better and im actually not going nuts trying to stay away from sugar so far everything is good about this product i think ill keep getting it as long as the price is good why not it works i have celiac disease so this product being gluten free is awesome
