I have been averaging 3 tabs of 10/325 Norco a day. I take it for numerous reasons...spinal stenosis - but it helps all of my arthritis. I stopped 2 days ago and hurt all over...I do this even when on the meds sometimes but the meds will pull me up. If I increased to 4 a day I am fairly pain free. But my Dr. won't do that so I am trying to just stop. I have fibromyalgia and I started with 3 tabs of 7.5 s a day when I crushed my ribs in 2001 and found it took care of the fibro pain - and the back pain I was having after a day of physical work. My Dr switched me to Oxycodone after an epidural - it's a terrible depressing feeling drug for me. He won't go back to Norco. Do you think I am having withdrawals from taking 3 tabs 10/325 (I only took a few oxycodone) for 5 years or this is fibro. Without the Norco I am always fatigued, achy, and confused feeling. I don't want the oxycodone and the second pain Dr. wants me on oxycontin patch. I think this is all insane.
