Yeah ECT! NOT a nice experience! It works though - if you're REALLY badly depressed I'd recommend it. I'm manic-depressive (they're trying to change that to 'bipolar' so we're not 'stigmatised' by the name - like you care about that when you're a loony) & a couple of years ago I went so manic that I crashed unbelievably after it. I was beyond any other help, so they shunted me off for a course of ECT. Gawd it was horrible, but I came out of my first session giggling. It relieved the severe depression, but also kept the usually cyclic depression at bay for 18 months for the first time in 20-odd years. VERY effective if you're in a genuine crisis.

But no, NOT a nice experience!!
