HI F Jean
Yes I do, and I think a lot of lupus sufferers do. There is good info here:

I forget words for things, calling a greenhouse a briefcase twice before I realised I had it wrong! I also forget or can't remember whether I have said or done something. i am also notorious in our house for writing down appointments wrong and then turning up at the wrong time, so my partner double checks things like this for me.
It ebbs and flows with the other lupus symptoms, the more tired and in pain I am the worse it is, which is pretty obvious really as the brain is too tired and too busy dealing with the pain to deal with other things I guess.
I think of it as my "woolly brain" and sometimes the wool is more dense than others. Putting the wrong things into the fridge (mugs, my phone and a diary amongst them) is one of my classics and I mislay my keys more often than most. I try to keep a sense of humour about it. The worst time was being in a shop and suddenly not understanding how to count out change, very humiliating. I was pretty unwell at the time and should not have gone out. Similarly when I am unwell I cannot navigate well, even on foot in familiar places I can get a bit confused.
I use a diary, the diary on the computer and my mobile phone facilities to help with all this memory. And sticky notes around the house help too.
Doctors call all this muddle brain stuff cognitive dysfunction, and it is a well known lupus symptom.
I think the thing to do now you are aware of it is explain it to those nearest and dearest to you so they can both understand and help you. And try not to be tooooo embarrassed there are a lot of us out there in a very similar boat.
Love
Sara
