Osomotor triggers- allergies by fragrances.
Being around certain fragrances that we breath up our noses can cause migraines, sinus problems, lethargy, nause.
As directed from my allergy specialist I removed all air fresheners from my house, threw away all fragranced body sprays, soaps.
I used baby powder for 3 months along with strict gluten/wheat free/ lactose free diet for 4 weeks. Felt fantastic no migraines etc.
worth a try.
