For me,
I usually lose a huge amount of time a day where I have no idea what happened. I am lucky if I only lose a couple of hours a day. Its been better than what it has been before. I have lost up to a month before and only thought I was in the hosp for a few days 3 max where it was actually way over a month.
Sorry that you are having headaches now though, their no fun.
Hope you are doing well!
Hugs if okay
