I know how you feel my friend. My eczema definitely has to do with the foods i eat, as i know when i eat really bad junk foods my facial eczema flares up really bad. So usually i dont eat anything but whole foods to prevent breakouts. I tried fasting, and it improved my eczema, but it was too hard not to have without foods because of my cravings. Have you ever tried the liver cleanse? I tried Andreas Moritz 's protocol in his book "the amazing liver cleanse" and a few days later my eczema definitely improved alot. It was my second cleanse. It was like my body was more able to tolerate things i couldnt before. I am definitely going to do more cleanses from now on. This is what helped me, maybe it can help you too.
