opiate dependence
"I took my first Vivitrol shot 7/31/12. 3 hours later I was having the worst withdrawals one could ever imagine. The worst lasted about 2 days followed by 7 days of symptoms like constant anxiety, sleeplessness, muscle spasms, then 3 or 4 days of regular side effects. My Dr. told me that I may not have been completely detoxed when I took the shot and that might have been the cause of my extreme reaction.  I'm going to get my 2nd shot on 8/31.  I feel that without the shot the possibility of relapse will be greater, so the benefit outweighs the negative side-effects.  I'll let you know how it turns out."
