Replying to ambien

bleh tonight i went to this one kids house for a party. and i was sitting on the couch next to some creep that was hitting on me. after he put his arm around me i told him i had a bf and moved away. he then was like 'ok, but hey do you wanna try this new drug called ambien? it makes you feel high with no hangover. you if i were you id take five cuz you look like a lightweight most people take like six' i said no, but correct me if im wrong but ambien is a heavy sleeping pill. and wouldnt five have killed me?
