I think with me it may be a bit of both. My memory hasn't been the best even before medication, but I've only been on mood stabilizers for the past year. I honestly don't know what's causing the brain farts. I keep a journal with me and I have different places around my house where I can write on a wipe-off board or post things on a cork board that I need to remember. Using Notepad helps at work because I just type as my customers are talking so that I don't forget what they just said to me thirty seconds after they said it. I don't want to have someone get po'ed at me because they have to repeat themselves. Then when I am done talking, I erase it and then I am ready to talk to the next customer. If I just rely on handwritten notes and my own memory, it's just a mess.
