I try to change my infusion site every 3 days. Generally, I hit the mark almost perfectly at 72 hours. Lately, I've been running the pump all the way to the last drop of insulin so my infusion sites go a little longer (only about 5 hours). I've just gotten lazy in changing them out.
Even before I started doing that, my pump supplies started piling up. I would get shipments for 3 months before I was anywhere near being out. I have a 3-month supply just sitting in my closet while I still use the current supply I have (about 1 month). My next shipment will probably be here within the month.
