My son has hurt his back... was taking Norco intermittingly for pain. Extremly has brought back his past terrible depression! And work has recently been very busy & difficult... this has definitely not helped but normally when this happens, he handles. Now the depression is returning. Says even though back is painful, this depression is horrible. Has stopped the Norco (hydrocodiene/acetimenophen) as of today... Has anyone had a similar experience? I read somewhere that Ambien is a very dangerous drug... thought that with Norco, that might be problem. Any thoughts? He is dreading going through the past depression again.
