Migraine associated vertigo.
I have BPPV...since 1966....
Singulair isn't an "allergy" antihistamine...it blocks specific reactions that could result in attacks of asthma, headache, coughing, etc...
Look into the above site, there is a forum there as well. I see there's a BPPV topic section as well.. I'll have to check out.
