Hey Jason,
I had surgery a few days before you! It does take some getting used to, all these fascinating side effects.
The best thing I can say about the balance is this: it gets better! (At least, it did for me!)
I've found that activies that push you, like the first time I went for a run, can make you feel very unsteady. But I also feel that it forces my balance sense to recover even stronger. Another example: The first time I played golf after surgery (just last week), I would swing, then 'freeze' for a moment and recover my balance. Weird feeling. But, the next time I was swinging a club, it felt just like old time. Sadly, so does my score...
Patience is never going to be one of my strong suits, but I found that, given time, the balance will get better. Hope it does for you, too!
Good luck going back to work - get your rest!
Josh
