I was on dilaudid in the hospital, however I have COPD real bad and it kept on giving me apnea at night (scary!). The Doctor wrote me a script for Vicodin 500mg for home. However, Im noticing the Vicodin, even when taking 2 as instructed, arent taking the edge off. What is everybody else using? A friend of mine mentioned I should call and ask for demerol. Any suggestions?
