Make sure you are staying hydrated, too. I use post it notes, as they stick to the desk or other surface. My mother, years ago, would use stick pins to attach things to her shirt!! Many people also use their phone's reminders for meds, to step away from the computer, etc. Our household uses the phone calendar, also, as we both get "bedazzled." Have you read Thom Hartmann's Attention Deficit: another perspective? It appears to match my attention span: like him, an afternoon Coke helped. This is a constant adaptation to life to be as productive as we all want to be: a friend said she noticed lots of us are A type personalities!
