opiate dependence
"Vivitrol has made me completely useless.  I was taking methadone as prescribed every day for the last six years. I actually cut my dose in half the last 24 months. But, I decided to quit cold turkey to get on vivitrol.  Now I am so miserable! I can only get myself to take a couple bites of food a day if I can keep it down. My head  is constantly throbbing.  I haven't slept more than two hours every night for at least a month. My body is so weak yet I'm constantly freezing and sweating. My hands shake all the time And the ringing in my ears is so loud I have a hard time hearing things sometimes. I find that I don't care about anything. I don't even want to be around my own son anymore.  I am not surprised people get suicidal on this drug."
