What to do if you have heartburn in Japan

So, I suffer from acid reflux..a more severe type of heartburn, and can't take my medicine to Japan because it is in a glass bottle , open and will probs leak or smash or something.
It is basic over the counter stuff so i decided to learn how to ask for it in Japan

I can already say "My stomach hurts" so figured it can't be that hard to say I have acid reflux..."ashido referukusu..."right?

WRONG

acid reflux is:
胃逆流性食道炎

igyakuruseishokudoen for those of you who can't read such crazy Kanji, myself included ofcourse.

I will *never remember* that

However the word for heartburn is

胸焼け
muneyake

and you use it with suru not aru... I can remember that no probs!

胸焼けがします！

On another note, i put my PC into Japanese mode to try and get some Idolmaster emoticons to work.. and failed miserably :( Now all my file directories use the Yen sign instead of / and my PC is throwing a bit of a wobbly, i'll sort it when i get back..maybe..
