I have been diagnosed with Menieres Syndrom also. Sorry to hear your going through a similar situation.
I've lived with Menieres Symptoms most of my life but have been lucky in that I've never really had long bouts of Vertigo but sure know what it is like. The hearing in my left ear abruptly ended roughly 20 years ago. My Right ear had good hearing until about 6.5 years ago when it too started degrading. I battled the fluctuating hearing loss over about 18 months which ended with my decission to get my first CI in my Left ear before the hearing was completely useless. The two months prior to CI activation was really rough since the hearing was so difficult to deal with.
I am now Bilateral CI and although I still have some ringing, for the most part the CI stimulation over powers it and I can hear very well now. The fluctuating hearing I can tell is still there but since the CI stimulates the nerve directly, it only slightly affects my ability to hear from day to day. Mainly I feel the pressure changes if that makes any sense.
I have had my CI in my left ear for 5 years and my right for 3 years. It has been for me a true life changing experience for me.
If your searching for other forums on Menieres, I have visited the Menieres.org site for support and to better understand what others have been through and where I found out about CIs.
Hope you had a relaxing and uneventful Holiday.
