Yes, I have used them for a while. I have mentioned that I used Dr. James Wilson's program for cleansing and stomach flora re-balancing. I did it 2 times. it worked really nice. However, it will take time until stomach starts working well. the body should become stronger, restore hormonal balance, etc.
You can read Dr. Hans Selye works. He explains that AF is HPA disregulation. Alternatively, look at dr. lams articles or the book. He borrowed a lot from Selye works.
