I tooo have the vision problems, also a feeling of im not quite grasping or my brain isnt processing what im seeing. Its really annoying.. the darkness thing you speak of I dont really have but I do recall about a week that I couldnt tell what time of the day it was if my life depended on it. MY internal clock completely shut down

So far ive been getting laser therapy on my brain and on one of my acupuncture points. some days I feel better, then I feel worse..... sometimes I feel not bad but my moods horrible, other days I am in a great mood but feel like a bag of garbage...
