Is Vestibular Neuritis Better Curable With Small Dose Of Valium Drugs?

Hello about 2 months ago I came down with a disorder called Vestibular Neuritis. I was put on antibiotics, physical therapy, steroids, valium, and isoxuphrine. I am off of everything except the Isoxuphrine.(dialater of blood vessels)..I am doing a lot better but still have some minor symptoms like fogginess, and tiredness, the nyastigma has gone away and I feel like I am at about 90%.I went off of the valium because I heard it was not good for patients with sleep apnea. I had sleep apnea and am no longer being treated for it because I have a mild case. I m wondering if I can get back on the valium. My doctor said I could experiment with smaller doses. I was on 6 mgs per day and took it down to 1/2 mg per day then stopped a few days ago. I was doing much better when I was taking it but with a reduced dosage.
