I've had/have lots of this, over the past 9 months since CK. Everyone is different, I think. I don't think everyone experiences this with CK, necessarily. On the other hand, there's a couple people on this forum who have had worse experiences with this than I have. I was initially kind of fuzzy headed in terms of concentration and ability to think clearly, but this improved over first couple weeks after CK. It's still very, very early on for you. I started developing more problems with this not quite two months after CK, and developed vision problems at the same time. Over the summer, my balance gradually deteriorated and I got a constant, floaty kind of feeling. I've seen lots of doctors for these problems, and they assure me I will likely improve over the next year or so. I'm very active, so they're not having me do any therapy. And there really aren't any medications that you can take in the long run which help you recover. In fact, some medications for "wonky head" can suppress your natural ability to compensate or recover (warning: I'm not a doctor, so this is just my opinion/experience).
Rest up a couple weeks, be active, insist on good followup, and know that most people do just fine after a few months. PM me if you would like more details or to talk, or look up my previous posts over the past several months which pretty much document my "journey." Stay positive - I still do just about everything I did before CK, and it hasn't affected my job or my family significantly.
