Hi Elizm. I just started using PEA, about 4 days ago, and I am praying it will help. I just happened upon hearing about it here. Someone was talking about it, and I started researching it, and finally bought it. Next time, I will buy the ones you suggested. I am starting on 800 mg., twice daily, for one month. I heard a Doctor from the Netherlands suggest that if you do not get relief on that dosage in a month, you can double that the next month, before giving up on it, so that is what I will do. That was from a video on you tube. I also learned that it must be taken with some sort of fat in your meal, to make sure it is absorbed. Have you heard that? Do you do that? I just read that from one person on an Amazon review. Anyway, it was utterly fabulous to read your post, and hear that you have had success. I hope that I do as well, because living in pain is utterly terrible.... Lori Renee
