... Dont work from time to time? I have been on them for 3 years I have always felt they are inconsistant but work most the time. I have stayed with them because I am able to have a better life on them compared to other meds The norco has been the best option when i have a pill not work though I have to take demerol for break through pain. I had a 800 pound storage box fall on my leg years ago then had cancer and lost part of my spine so pain med will be part of my life I am hopeing to minimize and feel I have as much control as possible.
