I also carry alot of stuff.
For work I carry my clipboard, a notebook, numerous pens, highlighters, pencils, a labor wheel, a steth, a reflex hammer, my reference cards, and my childbirth education notebook so I can work on my classes during breaks and slow times.
Personally, I carry my water bottle, my hand lotion and my hand sanitizer, my blood glucose monitor, extra supplies for my insulin pump, my wallet, a hair brush, a book to help count my carbs, and my food journal. I am sure that there is more but that is all I can think of now. Of course, I usually take my lunch and several snacks as I need to count carbs before I eat.
