ECT saved my life.
I do not regret it and would certainly recommend it to a loved one if it were merited.

In 2015 I had an intensive series starting with 3 treatments per week for 4 weeks. After that it has continued on a tapering schedule of maintenance treatments until I have reached the frequency of once every 4 weeks, and a total of about 60, I think.

I must be honest, there was memory loss, especially in the beginning, but that has improved over time as the treatments have grown farther apart.

The whole procedure takes the better part of the day. Of course, that's no surprise in my case since I have to drive 2 hours each way when I have a treatment. It begins an hour before the treatment with the insertion of the IV which is used to rehydrate your body and administer anesthetic and muscle relaxant once you're on the gurney. (Aside: Rehydrating the body serves to reduce the gap the electricity has to travel from braincase to grey matter, thus improving the quality of the treatment.) Once on the gurney, they hook up monitors for heart rate, respiration, and EKG. See, the ECT is inducing a seizure in the brain. The muscle relaxant prevents it being a generalised seizure, though, with the exception of one foot which doesn't get the muscle relaxant due to a blood pressure cuff around the ankle. This allows the staff to watch the twitching of your foot to determine when the seizure has subsided. The seizure, itself, usually lasts a little over a minute.

After all this is done, you get wheeled into the recovery area where you slowly wake from the anesthesia. For me, this seems to take 60-90 minutes, but I'm not very sharp when I'm waking up, so I may have that wrong.

I'm happy to answer any questions you have in order to fill out the picture of the process. You can ask me here or send a PM.

My next ECT actually happens to be this Friday.
