Re the dizzyness, I am now into week 10 of my PCS and really felt that this was one of the worst symptoms having not felt anything similar and I kept slipping on my feet for quite a few weeks. Am posting to let you know that all of a sudden I have had a great week and the dizzyness is slowly going away. I no longer need a cold flannel on my head or neck most of the time! Nothing affected it more or less, but I did find it fairly dehabilitating. Just posting to say that I hope your symptoms lesson soon and hang in there, you might be only a few weeks away from a good one!:
