(speaking from personal experience) the absolute worst disorder to ever have. lots of nausea, vomiting, dry heaving, hypersensitivity to
light & sound, etc. during an episode. the only medication to
stop an episode is Ativan. it's lesser known so doctors have a difficult time diagnosing. episodes can be triggered by almost anything, and triggers are different for
everyone (hormones, anxiety, excitement, changing of seasons, certain smells or times of
day, etc.). be prepared for lots of IVs and ER visits. also referred to as simply CVS. sometimes retching or heaving too aggressively can lead to tearing a hole in the lung and getting air trapped under the
skin (also happened to me).
