Hi everyone. I've had fibromyalgia and chronic fatigue for about 17 years. My sister has chronic fatigue and sinus problems that debilitate her. We have found out that histamines in food can cause these symptoms. We have been on a low-histamine diet for a month and now have started taking an enzyme called"Histame" (there is also one called Daosin)when we eat foods high in histamine. We are so much better it is amazing. I want to share this all over the internet. We also take plant-based enzymes. I don't sell these enzymes, I just buy them on the net. I hope this info helps someone.
