Been taking Norcos for almost 20yrs after accident... Last couple of years going through a lot of stress, have been also taking klonapins and valium.. I was taking 6=8 or more norcos.. I am now wondering if I am not just going through withdrawal from the norcos... I am down to 2 and a half norcos a day.. What I am wondering is if this horrible withdrawal is not just from the norcos... Maybe from the valium and klonapins.. feeling like on LSD/Speed..
