First of all I apologize if my post doesn't quite follow the typical format but I hope it's ok! (I've never posted on a forum before) I just really need some answers. I have been fentanyl dependant for about 6 months now, preferably IV but sniffing here and there. I have used a little methadone in the past to help with sickness and had no issue with being able to get high again once it wore off. Last week I took roughly 50ml methadone in the morning, and a little more later that day. Since then (it's been 7 days) I have not been able to get high again no matter how hard I try, or how much I do. I'm not sick at all, but becoming very worried and frustrated that I might never be able to get high again. Can someone shed some light on what might be happening? Or what I can do? I've been searching the web for days with no answers.
