Has a very bad smell. Find it so hard to swallow

A few days after taking this, I started to experience hallucination twice. It occurred not after I took it, but hours after I had taken it. I had headaches and seeing dark holes. I have stopped taken for about a month, and I had not experienced the hallucination once since. The only other time I had such hallucination was about 10 years ago when I drunk my first and only Coke Zero. Doctor told me that I was allergic to the artificial sugar substitute. The reaction I had with this supplement was not as severe as my experience with Coke Zero, but it was still disturbing enough.

I don't feel that I have had enough time on this product to see a difference yet. I just started school and I have been out school for 35 years and i seem to be doing good so far, so maybe they are helping more then I relize!
