Yeah, I'm jealous too. I managed to use it for about two weeks two years ago because a friend gave me a bunch of the IR's. Damn, that was the best rush I've ever felt. I haven't even seen a new Opana since then.
Anyway, Like I said earlier, I first started off with plugging some Adderall which felt great (along with drinking some coffee mixed with ensure, the vanilla flavor-trying to get some meat on my bones while still taking amphetamines), and then I left to go into the city so I could get my methadone. On my way back from the clinic I took 1mg of clonazepam.. It was a pleasant morning I'm happy to say.
