Hey, I was wondering if anyone has had or has considered ECT and what are your thoughts?

I have had Bipolar II for most of my life - although I was only diagnosed 7 years ago and in the last 7 years i've been on 14 different meds and combinations thereof but none of them work for anymore than a couple of months to a year or so - apparently my system starts to break them down after a while, or the side effects are extreme.

I was admitted to the local Psych Unit in February for depression for just over a month, and it was then when my CPN mentioned ECT briefly.
About 3months after that my mood shot the other way to mania and I almost got arrested again.
My CPN has mentioned it again, but I didn't press her and she didn't elaborate.

I've done a bit of research around it but has anyone had or considered ECT?
