I've been roofied downtown, it was a similar experience. The idiots I was with also thought I was having a psychotic break. If you can not remember it at all at and if it seems extremely out of character behavior for you even if you were blackout drunk, then I'd say yes, it was likely a roofie. Not everyone gets tired, some people trip balls. I apparently was crying, being mean to strangers (extraordinarily out of character for me), and by the end of the night I was apparently babbling about faries, saving the universe, and something something time continuum.
