Dealing with Memory Problems at Work: Any Tips?

I think all of us here being treated for epilepsy have bad memory problems. It’s actually been hurting me at work. I told my boss, and she says I should just write things down. I do that, but then I forget that I wrote it down, so apparently I ask the same questions repeatedly. And sometimes I don’t think to write something down because I can’t write literally EVERYTHING down. That would take up an entire encyclopedia! But sometimes I think I’m asking something for the first time, but I’m actually not, and it turns out it was in my notes after all. Or maybe not. Maybe I just forgot to write it down. Having a 💩 memory sucks. How do you deal with it, particularly at work?
