The smell of flavored coffee in the grocery stores make me feel nauseous. Especially halzelnut. It's such a cloying smell....feels like it coats my lungs.
That's not an allergy. Hazelnut coffee just plain stinks.
I can't stand flavored coffees, but hazelnut is the worst and stinkiest. Makes me gag and shudder. But if you got rid of my sense of smell for me, I could probably drink it just fine.
