As for the night driving I do this without problems now. For three years after my first surgery I couldn't even ride in the passenger seat without having to close my eyes due to dizzy feeling and too much movement going on with the bumps, lights and things whizzing by the window. Since my second surgery I am so much better.
I now drive at night without that "sick" or "unbalanced" feeling. It does take time for these feeling to go, but one has to practice this. Best to have a partner in the car for the first couple of trips if your really not sure about it.
I was forced into the situation, as I am taking evening class once a week and with time change I drive home in the dark. I stayed in the slow lane, I concentrated on the task at hand, but stayed relaxed while doing this. It was difficult, but after three weeks, I don't feel unsteady anymore. Frankly, I have more difficulty going down the ramp and walking to my car in the dark than driving in the dark!
You'll get there, just takes time and after time you still are not comfortable, then so be it. We are not all the same here and our vestibular schwannomas are not all the same!
