I've been using opiates for about six years now and a very strange thing happened to me the other day after I shot about three bags of Fentanyl. This has never happened before. Immediately after the rush I lost control of my body. I started kicking my legs and wreathing my arms and hands. I would make weird noises too. I couldn't control myself at all. This lasted for about a minute or two. Anyone else experience anything like this?
