I recall that in a presentation Dr de Meirleir gave, he correlated one of the overgrowths or undergrowths (which, exactly, escapes me) with mental 'spaciness' or 'blankness'. Ever since I went onto Symbioflor 2 a couple of months ago, I have noticed specific cognitive problems: particularly a kind of perturbing 'blankness' that makes processing information (e.g. text, TV shows etc.) difficult. Curiously, I then did a course of Haritaki which robustly improved my physical health but seemed to exacerbate the cognitive problems: Haritaki kills E.Coli (amongst other things), so it seems odd that both Symbioflor (an E. Coli probiotic) and Haritaki produced similar symptoms. I've noticed now that even when I am not taking anything, the symptoms persist. Shilajit, a herb that reduces serotonin/increases dopamine, fixes the issue, but can worsen my mood and insomnia. Has anyone experienced anything like this?
