Errr. Why has she said you'll need to take time off? If you've read "Pumping Insulin" before your pump start, other than the start date when they give you your pump, and have to do mandatory training, I got the pump and carried on as before.
I think it's daft to take time off to normalise things, as when you aren't living your normal life, your pump settings have a high chance of being different from when you are. But that's just my two penneth. As you might guess, I didn't take anything other than the two hours needed to get the mandatory training out of the way.
