When I went through ECT the first time around, I wrote down my passwords to the various online accounts that I have on a sheet of paper. This advice came from the book Shock by Kitty Dukakis and Larry Tye. It’s a great safeguard measure, and it was probably good to have my memory refreshed about those passwords anyway.
Keep a record of what you did each day during your ECT series. I think my main reason why I was able to remember a lot of the events surrounding my ECT treatments is because I wrote stuff down. Even just writing down your mood may be helpful in tracking how you are doing.
If there’s something you’re supposed to remember (even if you remember at that moment), write it down.
