My boyfriend is a long time methamphetamine and Valium user (dabbled in other things, but meth was the only SERIOUS issue. We have only recently come across being told about Naltrexone Implants being effecive only for withdrawl symptoms and/or if he uses meth, it "won't be the same". Today is 7 days clean for him and he will go to rehab this weekend for an anticipated 3 months. If I thought the last few months have been hell with this addiction, it doesn't carry a candle to the monster he has turned into for these last 7 clean days. Is there anyone out there who knows more about amphetamine addicts and Naltrexone Implants? I appreciate Naltrexone is primarily used for heroin addicts and alcoholics, however, my boyfriend can't be the only meth addict who has been given this implant....and there doesn't seem to be anyone either of us can relate to or discuss what he's going through on this one. Any feedback would be appreciated.
