I could be wrong, but i'm pretty sure that you can still find that stuff in Mexico. I remember reading quite a few posts of people who had been ripped off because they thought they were buying hydro or oxy or something, only to find out that it was Davron when they excitedly got home.

Personally, I wouldn't bother with the search -- the stuff rates up there right with aspirin in regards to pain killing ability, but it has that nice effect of being quite dangerous if you take not a whole lot more than the prescribed dosage. Good luck, but unless i'm thinking of something else (I just woke up, forgive me) then it's not really worth the hunt. If it's pain-killing you're after, the time spent looking for this could be better spent looking for something that actually works quite well.
