I think there are meds that slow down one's mind so the insiders wouldn't be as busy. there is no medication to cure insiders. One med that I was given was seroquel but I felt like a complete zombie. I took anti-anxiety meds instead to help with panic - then the switching didn't bother me as much - didn't happen as often.

To attempt to stop insiders from switching, its about going through it - finding out why they're there and with some hard work, you may be able to integrate them. But it does mean getting to know them and validating what they've experienced. Even if they don't integrate you can learn to get along and be friends.

I've heard of some people with insiders attempt to stop the switching by refusing to listen to the insiders and use all their energy on focusing on the present. Don't know how successful they've been though. Kind of like the movie "A Beautiful Mind" - Russel Crowe is dx with schizophrenia and decides he wants to overcome it - he refuses to listen to the voices in his head and practices living a normal life until he's living a life that he's comfortable with.
