Yeah I drop stuff in front of the door and tie a ribbon on my purse at times.
Bipolarartist,
I have often wondered "Omg" what if I lose my phone" I mean that is a valid problem that could happen.
I do actually have a small back up reminder here on my laptop desk page , just a yellow sticky boring computer generated one and I list T appts, Pdocs, Bills. But I have been known to just ignore the desk top in my rush to get on PC .
But having an actual alarm going off is my best bet for staying on track of things. One thing you do need to figure is what time of the day on average is the best time for the alarms to go off... Morning? Afternoon? Night?
Also make it a hellish annoying alarm sound, harder to ignore, and I always had a follow up alarm that goes off 15 mins later. Yes at times it seemed my phone was buzzing a lot , but I now manage my bills by paying then twice a month took a few months to get everything aligned to pay that way, I just called cellphone provider and asked to change my bill date , same with electric and stuff , I was actually surprised how easy it was to change the due dates, Maybe that could help you?
