I made a schedule of events on a post it note and put it on my planner pages to look at over the weekend. Even though all the tasks need to be done ON Monday, I'm not going to be looking at Monday events until that day, so the weekend/notes section was the best place.
I normally wake up pretty early (bleh), so 4m doesn't seem so daunting to me. Just in case, though, I am setting my alarm for 4am so I can take my antibiotic 6 hours before the procedure. I will also eat a little something and take my insulin. At 8am I have meds to take that will make me very drowsy - and then my appointment is at 10 am. I will have to take my antibiotic again 6 hours after the procedure - and that reminder will go on my phone, because I don't trust myself to remember - especially if drugs are involved!
Having all this lined up has relieved me of a lot of anxiety. Do you make detailed notes on post it notes?
