PS:

After I had filled out the survey on MindFreedom's website, I got asked to do a follow-up survey. It was more free-form; it was mostly text boxes to fill in your own stories and say what helped/didn't help.
There was a possibility to do yet more surveys if you left personal details, too. The form works even if you put in just a first name (and I made a fake one) and an e-mail address.
