sunflower oil switch

ive worked for chipotle for years, currently a gm, but since the switch from rice bran to sunflower in everything i genuinely cannot eat the food anymore.. it makes me vomit every morning. If i eat chipotle, i wake up throwing up the next day. it never fails. i dont know if im allergic, but i hate that i work practically 7 days a week 12 hours a day and i cant eat the food without throwing up the next morning. i only ever get rice chicken and cheese. Is this happening to anyone else??
