Travelling can be a source of stress for some of us, especially if you are not used to it and if you are an over-planner and need to be over-prepared.
Honestly, it is not something to worry about. This of the bare minimum that you will need in the country you are going to to survive:
- needles (if on pens)
- sensors/ glucose monitor and test strips
- gluco tabs (at least for the journey)
Those are the fundamental that you will need with you. Everything else is extra, and if you forget it, it won't be the end of the world. On an everyday basis, you test BG, you inject or pump insulin and you treat you hypos.
Do you use a glucagon kit every day? Do you measure your ketones every other day (not speaking about the guys on keto here)? Do you take 3000 extra needles, 20 spare pens and 30 pump sets with you to work every day? No.
Yes, you may want to be more cautious when travelling, but don't overdo it. Take a few extras and understand what to do in emergency, but STOP THE PANIC. You don't need a spare suitcase for your T1D supplies!
Think about what you need to adjust and how you can reduce the stress of managing your T1D before you go, not when you are already there. And allow yourself to f*ck up, it's a small proportion of your life, so you might as well enjoy your holidays and stop stressing.
You are NOT YOUR TYPE 1, so don't let your trip become all about it.
