Query: Have seen no benefits from this at all

After reviewing this product on Amazon I was expecting to see maybe some increased energy, or help with my acid reflux which causes bad breath, or something. I have seen no changes in anything at all and I have been on it for over 2 weeks. Not sure how long I am supposed to take it before I see a difference, I just thought I would have noticed something by now.
