There are few online resources dealing
specifically with MDDS. The most relevant one is Dr. Timothy Hain's
page about mal de debarquement:
Dr Hain's MDDS-related Page
In addition, the Vestibular Disorders Association maintains a page
on MDDS (which is at the moment just a link to Dr Hain's page):
VEDA MDDS Page
The Atlantic Coast Ear Specialists has a good page describing
other vestibular disorders such as BPPV (Benign Paroxysmal Positional Vertigo) and Meniere's Disease which sometimes resemble
MDDS symptoms:

Another page which describes the BPPV symptoms and the very effective
Canalith Repositioning Procedure is at
Benign Paroxysysmal Positional Vertigo
There is a great page which deals with the patient side of coping with
vestibular disorders called the:
Vestibular Disorders Hotsheet
There is also a general "dizziness" mailing list (for an MDDS
specific list, go to the support page),
which you can subscribe to by sending an email message with the words
subscribe dizziness in the body of the email message to
