I had it once a month. At first I was going 3x/week and then I weaned down. I find it helpful though I do have some memory issues relating to the days around ECT. I'm out of options with medications, though I'm still on a few. I did quit because I had memory issues and a lot of anxiety about going. I would still be doing it if I could get over my anxiety. I know that if I ever get very depressed again, I would do it.
