@Ragman,
Hi there,
I have had Menieres for many years but never found any relationship between the disease and ones diet!
It may help you to know that I discovered that when I started going dizzy, if I shut just one eye for up to 5 minutes (keep opening it again until desired effect occurs) my dizziness stopped and the diarrhoea and sickness did not occur.
This may well be a peculiar solution for me because no medical expert ever mentioned it and I never found another person on the web who had tried it.
I tried it because I knew that M was caused by conflict between muscles for space awareness, ears for sound, and eyes for spatial recognition. To avoid such conflict the shutting of eyes seemed the easiest way to try and control M. I soon found out that for me one was adequate!
I did continue with Tinnitus and eventually went totally deaf in one ear, but have been greatly satisfied with my discovery about my eye control for many years.
I hope this helps you too!!
