Oh, Nands, I come from a long line of women who lose the sugar bowl because we put it in the refrigerator, who never remember where we parked, who have lost more sets of keys than I care to think about, who have locked dogs in cars with the engine running... I feel your pain there.
A few tips from an inherently scattered adult ADD type:
I write down where I parked on sticky notes sometimes--especially if I am someplace new.
I worked to train myself to always put my keys in the same spot every time.
I am currently working hard to always, always, always look at my calendar every evening and every morning (it's no good to write down an appointment when I never look at the calendar!)
And I now keep the sweetener right next to the coffee pot
Good luck to you in the new job!! I hope your doctors will be able to provide you with some relief soon!
