this had me laughing.
i get pretty bad heatburn from really weird things. like i can eat fast food and steak and fuckin chips and salsa and be completely fine. however if i eat a bannana or a butterfinger, or like cookies/cake sweet baked goods etc. i will be fucked.
ive found tums to work for my general purposes, i have to eat like 6 of em at a time tho.
in the event you cant get any store bought remedies ifind those little red and white peppermints that they give you with your bill at resturants work really well for whatever reason.
