I am at 7.5 months and am doing a lot better (but still have some ways to go in my recovery - it has been a very gradual process). I'm not on any medications.

The mini-panic attacks have pretty much subsided. They were mainly an issue in the first few months, although I had the odd one after that. Time + consistently doing all the other "do's" associated with PCS recovery (day in, day out) has helped bring my anxiety levels way down.
