Activated charcoal helps with my brainfog

My biggest problem with SIBO due to which I cannot function normally is brainfog. During a flare up I sit in a chair whole day and stare at the wall or at the monitor. No creative thinking, no productivity, nothing that requires an active brain.

I recently had my B9 and B12 vitamins checked, and they are normal. I supplement B12 so it's not a big surprise, but then I thought that it could be the bacterial toxins that are affecting my brain.

I decided to try taking 400-600mg of activated charcoal early in the morning, I found some protocol to do it this way, there is a need to wait with food or other meds 2h after taking it, because it also absorbs meds and nutrients. It can apparently cause constipation, but my SIBO is hydrogen and more of a type-D, so that sort of evens out for me.

It did actually help, I'm not saying it's some magic cure because I still have 44 H2 in minute 90 in latest test, but I can at least function more or less normally and do something during the day.
