Several years ago I was eating plenty of Mono-Sodium-Glutamat (Natrium Glutamat) in processed foods, and using artificial sweeteners, mostly Aspartame. My wife went on this weight loss thing called the stack or some such and one of the three things you took was ephedrine. I tried it once, felt like I my heart and brain were going to burst out and detach from my body. I had extreme anxiety and a heightened sense of fear.
I am sure the fluoride and mercury did not help much either...
