Thanks. I first had unilateral ECT and it lifted me out of the depression for about 6 weeks, then I very suddenly plunged back into deep depression and was given bilateral ECT, that was about 3 weeks ago and I am starting to feel a bit better but the depression still has me in its grip. I am hoping to improve over time. Unilateral ECT is much better than bilateral when it comes to side effects. I had none with unilateral but with bilateral I lost a lot of memories surrounding the treatment and had a foggy brain for weeks. It has only worked partially for me but what was severe depression has turned into mild-moderate depression so I am happy with that but still feel pretty crap. As you said, it is different for everyone. I wish you all the best.
