Good topic -
I posted not long ago about the "fog" lifting at 6 months. Seems to be a timeline for others a well. It was as if a veil was lifted. I had bouts of dizziness and couldn't remember simple 5-6 digit numbers - ie a verification code etc. One day it was as if I awoke - like the movie (awakening).
Now my the critical thinking skills are much stronger and longer term memory is firing away. Recalling many things from years ago.
I had become concerned brain would never be the same. Now I feel as if it's not too late - though geezer-dom is calling.....
BTW - I am in mid 50's
