What are you drinking/eating? Some years ago during my time teaching in university I lived in a student dorm on a floor of 'natives' (Americans, Brits, Aussies, Canadians) and ten floors of students, many of them female, a considerable number of them with eating disorders. Some of them were gipping down the toilet and the acid corroded the pipes. But there was a lot of gipping and it did take some years for the stomach acid to corrode the pipes. As far as my limited knowledge of human anatomy allows, while somewhat stronger than say vinegar you don't produce that much acid in your digestive system to threaten the enamel on your teeth. If it were that strong, be sure it would be burning holes in your stomach lining and oesophagus on the way up. You can also drink tap water, which generally has alkaline elements added such as fluoride and chlorine. But as a disclaimer, it's donkey's years since I studied human anatomy. I could be mistaken. The binging/purging can also screw up your metaboilism, as I know from being an ex-binge eater.
