Talfrin,

Heroine, Methadone, Opium, Opiods all act fairly similarly. When you "stayed up" were you active or sedentary as in not wanting to move, not, necessarly, not being able to move. Those are the usual effects to the stronger opiods. Keep in mind that anyone can have anykind of reaction, up to and including death from any drug, food, etc. So no one will be able to tell you what you took for sure. Most likely was some form of opiod, cut with a little coke (where is that original Coke formula at?).
