how do you know you've OD'd? it's all about congruence..

I think you are right on the money for the most part. Tacitus posted this reply in his thread High performance communication: a 650 mu megadose of MEO-EST and putatives

If you can maintain congruency with the amount of pheromones you will be ok, but their is a limit for every individual that no matter how much you try or in Tacitus case, train, you won’t be able to keep up. That’s when the ghost effect will come in to play. I am not an agressive person, plus i’m type O so if I wear -none it has to be an almost non existant amount. Tacitus is smooth enough to pull of very high doses and even major od’s for most people. I am sure though there is a level that even Tacitus would get the ghost effect from.

It has also been said that if you go past the ghost effect levels people’s subconcious will just ignor it all together. It’s like cooking octopus. Time it right and it comes out tender. A little to much and it’s chewy, but if you keep cooking it for an extended period it will become tender once again even though at this point you’ve damaged your fine quizine’s integrity.
