How are you doing? I agree, the halo was the most frightening part for me also.
I couldn't believe I was actually doing it. I think I went into auto control just to make it thru.
It took about 4 weeks before my balance got better. I must've fallen once a day. Now I am in the middle of the programming. I am on 1 volt and have cut out my carbo levadopa. My dyskinesia and tremors are almost gone.

I hope things are going well with you. It will get better.
