HI I am having all the symptoms you describe and it give me some comfort that I am not alone with this condition .the doctors over a period of years originally said it was meniers disease and i have been taking SERC and sometimes stemitil.which do not make any difference . I am suffering distorted hearing in my right ear at the moment which makes me dizzy and tired the doctor now says its E.T D and says it should clear up itself in 2 to 3 weeks . i am totally deaf in my left ear with acute tinnitus i had a mastoidectomy many years ago..
