Ah, a couple more points about the supplies issue.
I also carry a spare battery, very small to take and handy to have, you can change over the second you get a warning and be done with it
I suggest that after a few weeks when you get a real feel for the essentials of pumping and drop away the extraneous bits and pieces, you put together a little pump supply bag and see if it's not quite small and easy to keep with you. I was suprised how small it all is once you streamline things, so it's surely worth a go.
You know, the biggest item that made it a pain to keep on me was the quickserter. Once I discovered that manual insertion was easy (if you've been on injections, it's a cinch) and that I get better results from manual insertion the removal of the quickserter made the whole package really minimal for me.
YMMV, as with pretty much anything diabetic.
