At this time it appears that there is no specific treatment that works for all who suffer from CVS. Different meds work for each individual. And for some, sadly nothing seems to work ! Many like myself have used a hot shower, placing a cool damp Terry cloth at the back of the neck to calm the Vagal nerve. Some sip on cool quality filtered water, Zofran melts sometimes work, Lorazepam, amitriptalibe, Phenergan, compatible, Regan, Benadryl works for some. And then there’s a cocktail of meds that work for some.
