K well i havent done it in months, but I say 4 as being alot cuz there hard as hell to find. I dont get it either cuz Im in high skool and thats the time you get your wisdom teeth out so skool should be rolling in Oxys or at least codein. Also I dont want to go up to heroin, I hate needles and its just way to addictive. So oxys r as high up the opium tree ill go.
