Same experience here, Tiggs, my friend had hers spiked and she passed out in the middle of the pub too. We were the only 2 females in a group of friends, the rest were rugby players (so pretty big lads), I was baffled as to why anyone would do that to her knowing they'd never get her alone to lead her away and rape her. I asked the paramedic this and his words were "there's a spate of this right now, they're somewhere in the crowd (rubber neckers) loving the reaction she's having to the drug, they get a kick out of it".
How sick.
She was taken to hospital and she came round a few hours later. She didn't know where she was, was scared, couldn't remember anything from the previous pub we'd been at and was upset. The nurse was mean to her and would not believe she hadn't taken drugs of her own accord. Neither of us have ever touched drugs.
