Amber: I am so sorry you are having so much pain. When I was on MS Contin, I took 45 mg two times a day. I am not a doctor but it seems 15 mg two times a day is not enough to help you. Is there such a thing as fentanyl cream that you could use, thereby eliminating the adhesive? Ask your dr. if that would work as a substitution. I hope you feel better soon. Regards, Lil
