I was on Invega Sustenna (injection) for 5 years, it basically saved my life. I was so out of my mind with psychosis I couldn't function and it was the one thing that helped. Unfortunately I ended up having to get off it last year because I developed some signs of Tardive Dyskinisia. After I stopped it I lost the entire 100lbs I had gained on it, so that was good.
I think it's a good med I just ended up having some issues later on.
