One of my daughters was poisoned like that one evening, but she started vomiting and didn't stop until everything was out ... managing to get help before she was beyond control. That is an extreme reaction. A milder version, perhaps like crack cocaine, which can give the sense of time distortion, lack of inhibition, a ruleless night world, more night-gangish survival mania than satanic. I had to change the sheets for my daughter throughout the night.
Knox and Sollecito admitted to getting drugged up and liquored up that night. Then, when Meredith was found murdered, they threw out all sorts of stories, ever changing times, events, memories, signed statements, secrets, feigned retractions, denials, fabrications, bizarre mop and bathmat boogies stories and ... well ... the list is long.
If it was accidental, it was not as bad as with you and my daughter. I'm sorry to hear that you went through it. By the time everyone figured out what happened with my daughter, 24 hours had passed and it's impossible to detect the drug. I don't really think that happened here.
