You are right everyone is different but vicodin, oxycodone,
hydrocodone, fentanyl, ete. are all drugs
used for pain such as muscle pain, bone pain, cancer pain or complications after cancer. They are never used for Bipolar treatment. You really do need to see a psychiatrist and let them know what you are using. You are only setting yourself up for a great fall. What happens when you can't get those drugs anymore?
