I Passed Out Off About 500-600mg of Pregabalin

I randomly woke up on the floor by my desk with stuff knocked over and i dont remember blacking out. it was really weird i took my medicine today (welbutrin) and i had some coffee after a decent meal about an hour after i took the preg idk if the combination had a bad interaction or if it was my body reacting bad to it but regardless i think its time for a break with pregabs
