I Went Out Clubbing With My Friends And I Was

I went out clubbing with my friends and i was designated driver so i had no alcohol at all, however, by the time we left the club i was light headed, slightly dizzy, and felt like i was going to be sick. I drove back home and then went to bed and about 2 hours later i was in the bathroom vomitting. i was so sick i couldn't eat properly for two days. Is it possible that my drink was spiked?
