I know the problem with dates. I have a similar issue with time. One person quipped a while back that I can tell you exactly what time it is, I just have about a 24 hour margin of error. One advantage of the meds is that it will frequently tell me the time if it's near time for me to take them...

Writing down is important for me too. I tell people that if it's not in e-mail, then the statement doesn't exist. I just don't retain auditory information...
