What comes out at 3.47am (post-it note to self: drink less coffee)

It started as a rash around the bottom of my monitor. Mostly references I didn't have time to check and questions for later consideration:

As it spread to the upper edges, motivational tips began to appear:

It began to creep from screen to pin-board to wall, then not just in books but all over them, and a few even sprouted in surprising places like the back of my phone and in pockets I never used. I found them stuck to the bottom of shoes I only wear 'out' and, in the kitchen, ingredients for saffron chicken were accompanied by pithy quotes from Barthes and McLuhan. The back of the door developed a reminder of my deteriorating mental state:

I really became concerned when I woke one morning to find my bedside table alive with lurid yellow notes like a swarm of paper butterflies – noisy thoughts I'd released during the night. Yesterday, I scratched an itch at my collar and my hand returned with a note attached:
In the shower last night, I looked down to see a pulpy yellow lump bleeding inky ideas down the drain. This morning, I dreamed I had a post-it note epidermis – millions of scaly yellow reminders obscuring what used to be a pink fleshy person. This is worse than the time I reached into my handbag for a pen and produced a mouse. It has to stop.

What affect does the inclusion of the notes have? Does it contribute significantly more than if I'd typed the messages? Immediacy. Trueness to form. I went back and reduced the size of the 'keys' note, because I think it works better smaller - to discover that after reading the text before it has more impact? If I were doing this in book form, I'd put that on the following page to delay the 'reveal' - manipulation of pace and reading experience by holding out, like a dramatic pause?
