This was a real pickle for me (not in EU/US). Auction site had no Meto for me. I hope you managed to find it.
Google using <R> (Meto generic name): "Buy Generic R without a prescription". There were some useful result. But also lot of junk. I found that if I add "in UK" to the mentioned search query that helps (they send everywhere but adding that made search more effective). There are several online pharmacies that sell this, I recommend none in particular, but they always have those famous erectile dysfunction pills. They're pretty much all the same. Sounds fishy but works - I was so suspicious I ordered from several - I now have too much Meto ...
Some people reported here that Meto is harsh on them. Alternatively, Domperidone is an option. It is slightly more available, in auction sites and across random pharmacies on the internet. It is considered as good as Meto with less side effects (EPS), but it's personal. For comparison:
