Rated Naltrexone (Vivitrol) for Chronic fatigue syndrome (CFS; CFIDS; M.E.)

I was put on low dose as a potential for pain management. Even at this microscopic dose, my side effects were insane. I took it at night, figuring I could sleep through any side effects. About 2 hours later I woke up with EXTREME restlessness and anxiety, to the point I was rocking myself for 5 hours and almost went to the ER. Even now 14 hours later the anxiety is horrible. Im clearly one of those who cant take this. I just wish it was out of my system already.
