"i am a chronic pain patient and have tried vicodin 5/500, norco 7.5/325, norco 10/325, percocet, percodan, darvocet, andffinally i have found relief with 120 mg of ms contin a day and percodan for breakthrough pain (up to 4 tablets a day as needed). i am now able to work a full time job, get up before noon and resume a normal life. i am so thankful my doctor decided to try the ms contin. the only issue is constipation, but it is controlled with miralax."
