PLEASE do not take Vivitrol !!! I was forced by a judge to take any MAT as long as it was FDA approved. So I agreed to start methadone in a state run and monitored facility. She agreed . When I came back to court to sign the agreement I noticed methadone had been scribbled out and Vivitrol was written in . I had a fit ! She told me it was her choice to switch it because she doesn't like opioids. I tell her that I'm in active SEVERE fentanyl addiction and that immediate administration of vivitrol would send me into intense hyper withdrawal . She says well it's that or a year in jail for possession of 60 bucks worth of dope so man up . So I have no choice , I tell the doctor/ nurse about my active use and she laughed, gave me the injection, and says " well i hope you don't kill yourself !" I go home and within 30 min or so I noticed I'm yawning , Oh Crap , I know what's coming. So in the end after 3 months of suffering unbearable agony and multiple emergency room visits and a massive bill later I still suffer from insomnia, stomach cramps , incredible headaches I didn't think were possible, pains in my upper right stomach, which my last doctor visit is suggesting a problem with my liver possibly due to vivitrol, and in my opinion a new form of PTSD that involves an unexplainable dread that I feel whenever I hear about opioid withdrawal . I know that last one sounds dumb but I'm telling you , I've never in my 40 years , and I mean never , had the displeasure and pure distilled panic of being in such a pathetic, state . I was a defenseless , vulnerable, pitiful , blob of slop , melting into the fake tiles on my bathroom floor praying God would have the mercy to help me out of this . I kept waiting for it to get better , it never did . I literally had to keep taking it until the doctor refused to administer it due to my poor physical condition and advised me to stop the monthly injections. He had to refuse the service to the JUDGE who actually argued that she new better . So I was "allowed" to take methadone and it saved my life , and I don't mean that metaphorically. The reason judges are pushing this is because the people who lobby for this company new people would never take this in high enough numbers to make it worth selling, so they went to criminal drug courts and lied about the effectiveness of vivitrol to easily persuadable judges , and they took the bait and here we are . Don't fall for it , if it sounds too good to be true , then it probably is , and believe me , it is .Read More Read Less
