I always have a backup, when i travel even a 2 hour drive away from home. I take a spare sensor, spare pump (Omnipod), spare insulin, and an insulin + dextro.

I always have a backup, when i travel even a 2 hour drive away from home. I take a spare sensor, spare pump (Omnipod), spare insulin, and an insulin + dextro. On vacation, I take a spare phone, in case my phone that manages pomp and sensor breaks down. It happened already twice on vacation in the past 5 years.
