After that, the brain fog was gone. It could have been by chance, but I have alleviated brain fog symptoms with antibiotics in the past, but its sometimes hit and miss. I thought the brain fog was due to down regulation or something.
But who knows, it's often quite hard to know what's doing what, there are so many factors at play.
