brain fog??

I have said for awhile now that I have brain fog. The symptom that leads me to believe this is not really a cognitive issue. The main thing I have is feeling somewhat drunk.

Its like there is a film in front of my eyes sometimes, alot of the times... I feel like its almost as if my contacts aren't strong enough and its blurry.. but i've had my eyes checked and i have the right prescription which leads me to believe its brain fog... anyone have this ?

Also, what is brain fog a symptom of--lyme, babesia, bart? i have them all.. my dr thinks im mainly struggling w/bartonella now.. has rifampin helped anyones brain fog clear?
