Well, yes and no. I will say this. The first time I railed an Adderall 20mg, from my first script... I was blown away, with that same kind of "where the fuck has this been all my life!" feeling when I did one, as I got from the first time I sniffed an oxy 30 ir.. Which gave me a very similar type of euphoria! The only difference is the oxy, was much more sedating that first time I did it, and became almost somewhat stimulating and sedating at the same time, when I became an everyday user years ago, and of course became less and less intense euphoria wise, as time progressed.. since then I have stopped using oxy though.. Adderall, on the other hand, I still use daily as I am prescribed it, and yes it did, at first, give me that breath taking feeling, like "WOW!" the same as oxy, but with the stimulated feeling it gives after the rush... So they are similar in some ways, but also very different in others..
I do kind of get what your talking about OP.. That euphoria they both give, is incredible.
