Just checked here and found your post. I have chronic Lyme Disease. The doctors wanted to label me with CFS, but I just would not allow it! I finally found a doctor who diagnosed me with Lyme. The symptoms are the same, except Lyme is treated successfully with antibiotics. I have tried this over and over again, and there is no doubt, that for me, Super Lysine and Lysine makes all the difference in the world when I have a flare up. It helps with the fatigue immensely. Super Lysine has other herbs in it, and it is wonderful, can be found at Health Food Stores, or ordered. It is definitely worth checking into. I wish you the best.
