I just enjoy oxycodone a lot.

It's more "stimulating", but in a weird kind of way...you still feel "opiated", which I link more to relaxed sedation, but it's mixed with a more...uplifting and "functional" high, I suppose? Heroin, while obviously very enjoyable, is a drug I find very sedating, when I've been high on heroin in the past I've mostly just laid around and drooled on myself lolz. I also have noticed that I enjoy being in social situations more while on oxycodone...when I use heroin I prefer to be solitary, alone with my own thoughts, and the presence of other people can irritate me a little.
All that is definitely all very much IME/IMO, though. I have noticed that pretty much everyone who loves heroin also appreciates oxy, though, and vice versa, with many who prefer oxy having a refined taste in dope.
also, I've been meaning to ask: is your avatar a picture of GG Allin on Springer? Because that's awesome lol
