Yeah I find the unpredictability of it really hard, things are going great and then suddenly u accidentally eat something or overreact to something..
I use 100% whey protein powder and it has 4g of glutamine in it, I feel its really good for my system but I guess everyone's different..it does have soy lecithin I think. Soy makes me feel good. Seems you're sensitive to soy..I am having a similar reaction have barely slept in three days (feel like s*&T). I think I reacted to magnesium supplements or zinc or something new in my diet I haven't figured out yet. I take anti histamines now and then and they really calm me down big time but I also don't want to make a habit of it. I have ordered lots of probiotics so I"m gonna experiment with those, and a different type of zinc as zinc is supposed to help tighten leaky gut (improve intestinal permeability) for ppl with crohns disease.
Its a really confusing condition and the medical profession doesnt help...
