Do you know of anybody that's been drugged before with date rape drugs like Rohypnol, GHB or Ketamine?

I was at a bar with friends (and my husband, thank God) over Memorial Day weekend. I completely blacked out at the bar 2 hours before we even left. I don't remember talking to the people my husband said I'd been talking to and I don't remember leaving the bar at all. I had 3 mixed drinks that night which is by far not enough to get me drunk. We live 45 minutes away, had to get gas and had to stop at my sister's house so I could use the bathroom. I don't remember it but we had a conversation, she said I just seemed super drunk and my husband had to carry me everywhere I went. We had to pull over so I could puke on the way home and I peed my pants when we got there. I woke up at 1 PM the next day with no memory of the previous night, only a sore leg from falling out of the car. I went to the hospital to get checked out, they said I had all the classic symptoms of being drugged but nothing showed up in my urine. Has anybody or anybody you know experienced anything like
this?
