Hi Karen, I'm sure you'll be fine. If you have any specific question when you start then ask away.
My only advice would be to do an early morning check on at least the first night . Also, not to be surprised if you have to change your total basal by more than you think.I quickly dropped from 16u of lantus to a basal of about 12 using Apidra in the pump (and I've reduced further since) but I have heard of people who have needed more.
Its also seems to be quite common that people start to think that they've done the wrong thing because it feels strange, you're a bit worried about doing the wrong thing and changing sets can be quite scary at the beginning. This usually passes quite quickly and it becomes so much a part of you that you forget you have it on.
If you haven't seen it already Pumping Insulin by John Walsh is the 'pumpers bible'
Good luck for Monday.
