I agree with Mark's suggestions. You want to ease back into things slowly to avoid a relapse. You don't want to lose all the progress you've made so far.

I am just about at the 5 month mark of my injury. During month 3 I had a couple of really good weeks. My most debilitating symptoms of nausea and dizziness had almost completely disappeared. I still had the occasional mild headache and insomnia, but I was so happy to finally be able to function during the day without getting sick. Unfortunately, after my 2-3 great weeks, I somehow relapsed or had a set-back (whatever you want to call it) that took me back to square one (and possibly worse). I have no idea what triggered it except possibly running more errands since I felt pretty good. I'm a stay at home mom, so it's not like I was thrown back into a work situation. Everyone's experience is different, and I hope you are close to recovery, but I just wanted to chime in and stress how important it is to not push through pcs. It can be such a rollercoaster ride.
