Sausage! Oooh! Big reflux trigger for me. Pork is naturally full of sulfites, and then there's the spices. Pepper, garlic, onion ...all big triggers. Fat can be a whole separate category of trigger.
Yes, getting a reflux going can last a long time when you realy do it up wrong. I don't know about 2 weeks, but a day is within my experience.
Make sure you get everything you ate in your food journal, along with your reactions. There's a good chance you ate more food the same meal or at least the same day that added to the reaction. Did you eat leftovers? Everything you ate for that 2 weeks is suspect.
