Memory loss is side effect of Fioricet addiction. I'm trying to kick a heavy addiction to this monster and I knew I was having trouble remembering little things but just this past weekend my wife told me about things I had done and forgot about. She said my personality did a change for the worse. It really made me sad and scared, at the same time.

I would say to anyone using Fioicet in excess of what is directed by your Doctor, try to find a way to stop. If you suffer from migrianes, try Fioricet only as a last resort and use as directed.
