I am a 36 yr old male with hip problems. About 3 months ago a family member offered me a few boxes of fentanyl patches. 50mg/hr for 72 hr. I applied the patch and it semmed to have little effect. So about a week in I started cutting the patches in half and sucking on them. The pain instantly went away and I loved the euphoric feeling. In two weeks time I was up to four halves a day (2 patches). My family members supply seemed to be unlimited. I just ran out Saturday October 13, 2012. I never expexted this type of reaction from my body. This is hell. I cant sleep, I can not sit still, my skin is constantly crawling.......etc. Does anyone know how long this will last? Please reply. Thanks
