Need a program to keep a daily medical journal

[Brenda_D]

Do any of you have any suggestions?
After making notations of various problems and symptoms on my calender, I decided a better way would be to have a journal or diary type program on my pc, to note daily problems.
I've looked at several, and found a couple I liked, but they are not current and they are not free.
If I pay for a program, I want to make sure it's updatable, at least for awhile.
I did find one supposed freebie, but it was really nagware (donate $20) and it was very basic.

Thanks! Brenda
