Happy to report that I do NOT have wonky head.
My balance was never that bad after surgery, as the balance portion of my nerve was pretty much destroyed by the time I was diagnosed. I had many years for my body to compensate. I was a bit unsteady, but never required a cane or walker, and pretty much just took it a little slow and made sure there was something nearby to grab onto if I needed to (furniture, walls, small children, etc.). I'd say by 2 months, my balance was to the point where I was the only one who noticed my little "bobbles".
I did have more of an issue getting used to the SSD and that gave me sort of a spaced-out feeling at times, but I think that was more a matter of my brain learning how to filter out noises and my one good ear getting used to doing all the work. It took about a year for that to go away.
I had some exercises given to me by PT in the hospital, but since I am a PT, I just tried to incorporate those things into my usual routine - walking on uneven surfaces by going to my daughter's soccer practices, walking while turning my head at the grocery store, etc. Pretty much whatever movements were challenging for me, I just tried to do those until they got easier.
I'd say I feel normal now - there are days when I get really tired or have a cold or something that I feel a bit wonky headed, but I don't think it's nearly as bad as true wonky head. (Do you think they'll add that diagnosis to the medical dictionary?)
