I've been taking Norcos for 3 years. I take between 4-6 a day, I've tried to stop several times, but I hate the withdrawals. I get the chills, then hot flashes, the cold sweat, my bowels are irregular, stomach cramps. I feel restless in my own skin, but I think the worst is the terrible mental anxiety. I recently lost my job because I would stop taking these and get so anxious I felt that everybody could see me uneasy and it would make me crazy.
