It's made me not need my 3pm coffee which is insane. Now the energy you get is not the jittering kind and is not like that noticeable artificial jolt you get from a monster energy drink. You just feel, how should I put this, "normal", like you had an amazing sleep. Well rested, alert, but normal--you get the sense, "yes..this is how one ought to feel." Again, nothing crazy, just a, how should I put this, a "heightened normal." (Which is what you want!)
