Hmm....I posted in the other ECT question, but I will here too.
I had ECT 2 years ago. I was in a depressed episode and nothing was helping. I had 12 treatments, 8 while I was inpatient and 4 as an outpatient.
In the hospital, I had them in the morning and was fine by dinner. I had a headache and felt a little naseau when I woke up. I took a nap the whole afternoon. It actually does not take that long. It takes longer to provide the anesthia than the ECT treatment.
As an outpatient, I had them MWF in the morning. I was dismissed by noon, but had to be with someone and could not drive myself. I went home and went to sleep. The day is shot.
PS: Some people say they pull their muscles, but they give you a muscle relaxant when they put you to sleep. You are like a rubber band!
I had no memory problems or confusion. Mostly just headaches and naseau. It really helped me when other things did not.
Good luck with your decision.
