Sometimes it feels as if I can't remember to do anything. Basic things, like "shower" or "take meds" or "feed fish"...
So about four years ago I came up with a system that really works for me.
This system allows me to usually check off most things on my important to do list. If I get to check off things in my "Extras List", even better! I tried to put most things under extra because I always feel more accomplished when I'm able to move on to my "Extras List".
I often write my list in a gmail draft so I can access it from any computer or phone, but lately I've been using Microsoft OneNote 2007. Now I have multiple tabs of different things that I eventually need to or want to get done.
I hope this might be helpful for others with POTS who are struggling to remember what they're supposed to in a day.
