Wow, this stuff is amazing! I just got my sample in the mail from someone. I was feeling tired because I didn't get any sleep last night and I took two tablespoons and I feel WIDE AWAKE now. Before you go thinking it's all in my head-let me just tell you I am the biggest skeptic- I don't believe ANYTHING until I try it myself, etc. I was fully expecting this to take a few days at the very LEAST-I know any type of supplement, especially liquid-takes time to build up in your system and notice results. Soo I was VERY surprised how I immediately felt better. I can't wait to take more of this and see if it's just a fluke or if it really did make a difference!!
