Hi Scott,
Yes this is entirely normal, as they told me its that the brain has something else to deal with and decomp

is exactly whats going on! Subs is right as you get better you will find that colds effect you less and less. absolute best thing you can do is move around again and carry on to give your brain a chance to retune.

You should be as good as new within a week or two tops. I am the midst of yet another cold and its not really hit me that badly yet (*dare I write that*) dizzy wise. But geeze normally this would put me into the state that you are decsribing, who knows what tomorrow will bring! LOL. You will get back on track very soon, keep on trucking, you will get there!
Emys - I know you are having a rotten time of it, chin up, this will pass.!!
