I'm prescribed 10/325 of Norco's 4 times a day. I'll take 2 at one time for breakthrough pain and have noticed 2 months later I have developed a tolerance to them. I was hoping to talk with others here that have experienced the same thing about this and what they did. I guess if they are not working I should stop taking them for a few days, maybe hope the tolerance goes away. Thing is my job, after I do a few clients my back pain can get pretty bad. Any suggestions? If I did stop taking them for a few days, would the tolerance subside? What have you done in this situation? Thanks in advance.
