From what I've been searching the antacids you should use for the SN method should be histamine-2 blockers, like Zantac, but apparently these are banned in Europe, you can't buy them here. Would something like Gaviscon do the trick, or should I not even bother? But how crucial are they? The suicide-wiki even says "Using antacids (also known as acid regulators) is discouraged. The antacid section of Suicide Wiki is provided here only because you will encounter with antacids in the PPH", which I don't know why they say this since in Stan's guide it is mentioned
