I did ECT, and the only thing I got out of it was some short-term memory loss. But I know other people that were getting it at the same time had success and were even able to get off their medications. Everyone is different, and there's no way to predict who will have success and who won't. I'm glad I tried it, though, because I can leave this world knowing that I tried everything possible.
Good luck! I hope it works for you.
