In a local store where they used to sell it, I've seen Midnight Poison in its place.
I've heard this one was terribly reformulated into something quite different from what it was, and by the time I got around to it, I thought it was quite foul. This might be more of a mercy killing than a discontinuation.
Tendre Poison was released as a lighter, younger alternative to Poison, so maybe that's not necessary now that Poison is a lighter, younger version of itself. It's been tenderized!
