Hi, I have recently got norco for my back pain. I want to know why, although it gives me MUCH more euphoria then vicodin lorcet and lortab, because of the 10mg's of hydr. and only 325mg of ace. it gets me more dizzy and hurts my stomach more. i thought that the acetemetaphine causes the nausa... even when i only take 3 of them i get really sick. i can take 4 vicodin and just feel a little sick but 3 norco's kills me. thanks for reply.
