One thing I bought was a small tape recorder that fits in my purse. I can use it whenever I really need to remember something and play it back later. It has helped quite a bit.
I make lots of notes, too but I forget to look at them!! LOL! Since multitasking is something very hard for me anymore I try to do one thing at a time and really focus on it and to try and not rush with anything.
Believe me you are definately not alone!! I am surely an MS head!
