I am on my second day on 90 mgs. of Oxycontin, from 100 mcgs. of Fentynal patch. I really thought that 90 would be enough to make the change. I am in bad pain. It's just not enough. I am taking the Oxy 90 x 3, and 30 x 6 for breakthrough pain. Is there something wrong with me?!!!. I am going to have to call my doctor and ask what adjustments need to be made?. My doctor warned me that I would have the same old problem with the time. I am happy with 90 x 3. Every 8 hours is a generous time for 3 dosages, so It is just not strong enough!. Well, I guess I should wait a couple of days and see how he reacts. As far as the "no crush" formulation of the drug, I am happy they are doing the change. I got on a different website, and everybody is getting off of Oxycontin saying that the new formulation does not work for them, so they are switching to something else. Come on!, they must think they're doctors are stupid!. I wont get so many dirty looks from my family, or the pharmacy now that you can't crush them, or whatever some people want to do with it to get high. That immediate release feeling you can get from your breakthrough medications if it's so important to you!. Anyways, I'm in pain, and I can honestly see myself on 160 mgs. of this Oxycontin, 3 x 8 hours. Am I crazy?, or is that a good number for someone who just stopped 100 mcgs. of fentynal, because I needed a dosage increase, but did not want to go any higher with Fentynal?
