Courtney, I am curious about your not eating carbs all day. You were not getting any basal, so did you have high blood sugar? Did you inject some basal? I have not had any basal insulin on hand since I started pumping. The pump provides both basal and bolus.
My blood sugar stayed consistent around 140 so it wasn't that outrageous. I had no insulin all day, until I got home and my new pump had arrived. I don't have any basal insulin on hand either and all I had were syringes which I did carry with me that day just in case. But I was only going to use them in an extreme situation.
