Well, I don't think it gets much better than a high dose of oxy up the nose and a little xanax about half-way into the high and more during the comedown to bring some fantastic nods. Really, any opiate will do. But, to be honest, I do most drugs alone... ecstasy, coke, opiates (as mentioned), benzo's, even alcohol. Perhaps it's due to the fact that I don't have too many friends who are into heavy drugs. The only drug most of them do is weed and I can't stand that shit.
Peace
