Some weeks ago, I had a relapse occurring within a few days of taking home brewn Tibicos probiotics. The gut symptoms have disappeared, but I still feel mentally and physically impaired. It's possible that this is a coincidence, but I've also noted that the usual relapses tend to happen shortly after meals but without any apparent reason. In both cases the recovery takes weeks or months. Since the start of my illness, my digestive system has slowly become more sensitive (mainly to "industrial" foods). I should mention that I tolerate normal store bought probiotics and there is some mild benefit as well. I'm wondering what is happening there. Is this some immune reaction, or indication of an unhealthy microbiome? How common is this in other patients? I know that this topic has been studied, but I'm not informed about it. What is known, and what is believed?
