My husband gets Fioricet for headaches. He doesn't take them as prescribed and takes 10 or more at a time continuously. I have never seen a person act like him when he is on this drug. He becomes a different person he becomes argumentive, won't let stuff rest, can't tell him nothing, angry, abusive and on and on. He just went to jail a couple hours ago for fighting with a neighbor. Luckily this time is wasn't me. He refuses to believe this drug changes him like that. Is this common with abuse of this drug.
