it was probably a mix of being cold and the large amounts of GHB that she had in her system. I mean, she had been drinking pretty heavily (shes one of the people I know who REALLY can stand her liqour) during the night, so it was a dangerous cocktail she had in her body. The doctors said that the GHB alone would have been enough to kill her.
Yeah, its sickening that people actually go out with the intention to drug someone, it was a reality check when it happened to her, never leave my drink out of sight after that.
