I second (or third lol) Fruit TIngles. Actually I have some sitting next to me right now LOL!

BLEH bi-carb... yep it would work though because thats mainly whats in fruit tingles (its what makes them tingle I believe). If you're going to try a bi-carb drink, I would go with Salvitol. Tastes way better than plain bi-carb too! I use it for nausea as well, really picks me up when I can't handle much in my stomach and takes the nausea away. I don't use it too often though, but I am 99% sure it is completely safe (well Bubble is still here, healthy and active as ever and I've been using it for nausea, and then heartburn, since 8 weeks!).

Milk actually causes heartburn and reflux in me (PITa cos I'm craving milk ). Also things like onions, tomatoes, and garlic set me off every time. Another PITA cos I want lasagne!!!!!!!!!!!
