Does this sound like I got roofied?

I think I may have been roofied (or ghb-ed) this weekend. I only had a few drinks and I usually tolerate my alcohol very well. My friends said I was having a great time once second and the next I was sitting down unresponsive to anyone and then I started throwing up. I blacked out from about 1am until the next morning. My friends were smart enough to get me to the hospital and apparently I rode in an ambulance. At the hospitol I was hooked up to an IV and given a breathing tube. They didn't pump my stomach or do any bloodwork to see if I had been slipped something. ( I assume this is because I was in the ER on a busy Saturday night) I can't remember any of this and am having a hard time believing it was from the few drinks I had. The next day I didn't feel very hungover, but I'm very dizzy, and my stomach is a bit upset. I just felt a little out of sorts, but not like a normal hangover. Does this sound like a reaction one might have to a roofie or other similar drug?
