The opiate only medicines are VERY hard to find in ski resorts, it would seem. As each town only has one (maybe two if you're lucky) pharmacies, it's hit and mostly miss that they'll have anything hard to come by and ordering it in is unlikely up a mountain. The best I managed to get was 'CodéDrill' and 'Néo-codion', both codeine only cough syrups, the former is optimistically described as cherry flavoured, but tastes more like uncooked pastry and flour; the latter just tastes like absolute shit - both hard to choke down. Codoliprane is very common as was mentioned and you get no funny looks asking for it. However, buying another bottle of codedrill 2 days after the last from the same woman was a dodgy; I hoped she might not recognise me with my gear on but she quizzed me about it and then gave it me anyway. If only it was that easy in England!
