You won't feel a thing. They will give you anesthesia and a muscle relaxer so you don't actually physically seize. When you wake up, you might have a headache, but personally I never even had that. It is a quick treatment. You'll be awake within minutes of the treatment. I was usually fine to function the rest of the day, perhaps needed a nap later in the day.

As far as memory loss goes, I had very little problem with that. The most I noticed was a loss of memory for the time surrounding the treatments. I had no long-term memory loss or lingering issues.

Everyone responds a bit differently to ECT, but usually it goes well for most patients. The type of treatment can make a difference. My treatments were unilateral which is less harsh on memory. My husband's were bilateral and he had a bit more disorientation and memory loss than I did, but he too recovered nicely with no lingering effects.

I hope all goes well for you.
