Shirelyann,
  I see a lot of patients with syncope--or fainting. There are many
potential causes: low blood pressure, a funny heart beat, "vasovagal"
syncope--a simple faint brought on by lots of stresses. In my
experience, Meniere's causes extreme dizziness, and can cause some
bursts that may make you fall, but not usually lose conciousness.
 The usual evaluation for faint involves cardiology, neurology and
possibly ENT. Some of my patients get put on a tilt table to see if
their blood pressure falls as they stand.
 Meniere's is thought to be caused by excess fluid inside the
semicircular canals of the ear: it causes vertigo, ringing in the ears
and decreased hearing. The usual treatment is low salt diet, a
diuretic (fluid pill) and possibly a vestibular suppresant--either a
low dose benzodiazepam or meclizine. It's a clinical diagnosis--
there's some testing, like ENG--which tests inner ear function, and
more sophisticated testing like spinning in a chair, while watching
your eye movements.
 The key to treatment is getting a diagnosis. Until then, be careful,
stay hydrated. I hope you figure this out soon.
