Has anyone here done ACT before? What is it like? How is it different from the standard treatment?

I'm about to start it and I'm worried it won't help. A lot of people tell me ACT is good stuff but they won't say how it's any different from what I'm getting now. Any info is helpful.

(I don't know if this is the right subforum for this, mods feel free to move it if there's somewhere else better)
