Hi all, This is my first time posting on the forum. I've had CFS for around 4 years. (No formal diagnosis, but relate heavily to the symptoms and am currently a patient with a CFS clinic in london) I just want to say hello! I have been a bit of a lurker for a while, and thought it was time to start posting - although I most likely won't be on here too much due to avoiding EMF's. (YOU KNOW THE STRUGGLE.) I wanted to chat to you guys about histamine intolerance, as this has been a particular stand out symptom of mine of recent. I've been alcohol intolerant since as long as I can remember, I'd say 5 years. When I first started drinking it was I think the first 2 years I was fine and then got alcohol intolerant. (Although I am an introvert and have never drank much) A year ago something terrible happened, I developed histamine intolerance to both caffeine AND chocolate. I tried chocolate three times during that time and all of those times ended up in hospital. I also have a leaky heart valve and possible mitral valve prolapse which likely does not make the histamine situation any better. (Oh, how cruel life is..) I've had SIBO for two years, currently seeing a nutritionist and will start herbals soon. I read sibo can cause histamine intolerance and wanted to ask if any of you have ANY experience with this symptom or of beating it? It seems primarily to do with methalyation pathways? Earlier I had chicken provinical which had white wine in it by accident - such a mistake. Even alcohol that has been cooked out causes these symptoms! Even if I beat the sibo, I honestly think the issue of histamine intolerance might never go away. Anyway, would love to know your experiences and lovely to meet you all. I'll be posting on the forum any useful bits that I have learned from this horrendous condition.
