To the issue of the injection sites, I like the idea of marking each day's shot with a small bandaid; never considerd that. But when I was starting up, the Tymlos clinical educator told me not to be so obsessive about it. She suggested visualizing my belly in seven big areas ( not closer than 2" from the navel, and not above the level of it) and rotate from one to another area each day of the week. So, Monday is upper left, Tuesday is lower right, etc. I've seen a couple things online that say that as long as the sites are a finger's width apart, it's fine. If you only hit the area once a week, even you were to get the needle into the same spot it should be all healed from the last time.
