Few things.
First off, Dont eat taco bell or anything like that for a few weeks.
Go to walmart or a pharmacy and get Alak mints. Made by alkasletzer. Typicall you get reliefe the minute they hit your tongue.
NEVER chew those or any other mints. Let them disolve slow and they will work better. Star lite mints will work as well.
Lastly.
Have someone you know cross the border and grab you a few bottles of Omeprazole
http://en.wikipedia.org/wiki/Omeprazole
Take that for 7 days straight, and then stop. If you Know you will be eating something bad like that take 1 a day for a day or so ahead and after the meal.
