Instant noodles fogged me
I hope I'm not jumping the gun, but it feels like I may have solved my recent (last few months) bout of brainfog-like symptoms. This time it was triggered by instant noodles/ramen. I stopped eating that a week ago and have felt a gradual improvement, last night and today felt remarkably better.
It seems I'm quite sensitive to diet and supplements, due in part to my job which involves high volumes of high complexity tasks and frequent context switching. Small changes in my focus, cognitive state and mood get amplified.
One previous trigger was coffee, but I was very stressed at the time; I have been drinking coffee again recently without negative effects. Another was a supplement I used - Himalaya Mentat. Interestingly, at first it solved the problem with coffee, but after a while became the cause of the problem.
Just sharing in case it helps someone else. Ymmv.
