I have a little bit of it- I'm not very organized at all anyway.

So I have had to get myself a bit more organized just for these same reasons.
Do you have a dedicated space for all important notes and folders for medical, bills and things like that?

I keep a calendar program on my computer {Anytime - but theres' other ones out there} and it pops up every day when I start the computer up- so I am sure to remember appts and special days.
and every day I add anything that i need to remember.

I use sticky notes on computer screen and the refrigerator & I have a regular calendar on the refrigerator too - so the info is in 2 places.

I keep sticky notes at the phones to make any notes that i need and then stick them on fridge or computer- so i can add them if needed.

For the appts and such- ask drs for a copy of any notes and tell him you have trouble remembering the details of the appts.

they also have those mini recorders - ask if you can record/tape the appt so you can remember what they say.
