Annesse, that would be really cool if a missing enzyme was responsible for all those chronic diseases. I was diagnoses with Fibromyalgia. I believe the cause was do to shock to my body from Vancomycin. This is what happened (short story). I worked at a hospital and contracted a Staph infection (MRSA). On receiving my 3rd dose of intravenous vancomycin, my world had collapsed and I got this severe allergic reaction to the penicillin where I couldn't move my muscles several hours like I was paralyzed. I had no problem breathing, but my muscles just wouldn't work, from there on I went through numerous test to be diagnosed with Fibromyalgia. So you see, Vancomycin not only destroyed all of the bad bacteria, it also killed off all my good bacteria and with that stress on my body it triggered Fibromyalgia and maybe killed numerous enzymes along the way.
