That's why I asked just in case. As for how fast acting....I want to say that it didn't start acting up in the dreams until a few hours after a flight from China to New York and then a few more hours before it was realized to be poison and not just feeling sick....
Currently my symptoms of cramping, heart palpitations, and sweating. If it is the poison and follows the path of the dreams, it should be another couple of hours before the poison starts to reach my brain or heart.
