Hi Toomutch,
I have no experience with ECT, but I did watch a program from PBS called "This Emotional Life". In the second segment (of three) they follow a teenaged girl named Caitlin through her struggle with depression and is given ECT treatment after other meds/therapy failed. It quite interesting as they show the entire process and the what's behind it. It seemed to help her but I don't know if they followed up later.
This Emotional Life
It's an interesting program. I downloaded it from Itunes and it cost $5.00 for the entire series of three two-hour episodes. A great deal!
Anyways, maybe you'll find it helpful.
