Sorry to hear your troubles Jeff.
I knew a guy who's wife was born deaf. I believe she was one of the first to receive this procedure.
From what she told me, it was a huge success. The biggest issues she had was learning to hear and know what she was hearing. Also, since hearing was new for her, she would not be able to tune out certain noises like other peoples conversations or white noise.
Since you have been able to hear in the past, I think you wouldn't necessarily have those issues since your brain has already learned to deal with it..
One thing you may have is super sensitive hearing but it may go back to what i was talking about before with the brain. we were at a restaurant with my friend and his wife. She was complaining about a noise. we all had to really listen hard for it and decided what she was hearing was a high pitched frequency from a television which was on but not playing. Although we could hear the frequency, it was something we tune out.
with that being said, I am not sure if she was just sensitive and heard that noise as "loud" or if her brain just hadn't learned to tune it out.
Best of luck Jeff, I had a good chuckle at your joke.
