I had vertigo on and off for years, part of the problem did seem med related. I was definitely having "brain zaps." Do not decrease any meds before talking to your doc, since that can be dangerous as well... Depending on the severity of your episodes, you need to either have a plan set up with your doc on what to do, or go to the ER. I passed out several times and never went to the ER... In hindsight, the normal/smart thing to have done, would have to treated it like the emergency it was. I was so focused on my pain at the time, it was just another thing on my laundry list of body failing me.
