If possible store your insulin in separate bags, half in your hand luggage and the rest in your suitcase. Remember the hold of a jet can be very cold and could possibly freeze your insulin, so if you are flying by plane ask your partner to keep the other half of your insulin in his or her hand luggage. Wear an ID bracelet, neck chain or have a card with details of your condition. Never assume anything. Secondly take 1 ltr bottles or cans of Lucozade, once again this is not sold in France.
Foreign places mean foreign bacteria.
Do not drink the local water and remember ice cubes are usually made from local water. Remember although you may be using a pen device, always take a supply of unopened syringes as you can draw insulin from the cartarage used for the pen device and a spare pen which you can get from your diabetes clinic.
