I totally think you should consider maintenance ECT. I had ECT several years ago and it helped me a lot. I got headaches from it, too, but they can pre-treat you with Advil, or give you a shot of Imitrex or something and that works great. My memory problems weren't too bad, just a little annoying, and they cleared up with time.

My psych is recommending the hospital for me right now, and he's mentioned ECT. If I can't get out of this funk any other way, I will do it. I think it's extremely courageous of you to be thinking proactively about how to help yourself before you get to the point where you don't care!! Best of luck!!
