My husband is 5 months post treatment now. The ringing in the ears comes and goes as well as the shakiness. I know recovery realistically takes 1 to 2 years. He gets tired so easily and has little energy at times, and he is still struggling with memory issues and overall cognitive functioning. I think he is petrified of returning to his high demand career because of these struggles right now. He is so much better than he was 2 months ago, but it seems there is still a mountain in front of us. When did any of you see improvement in these areas??
