I'm so excited, I'm going away with my boyfriend and his family for a long weekend at the end of the month!
Having diabetes has never stopped me going abroad and it shouldn't stop you!
All you need to do is be slightly more organised then others. I always remember to pack enough medicine with me, take a letter from your hospital stating you with be carrying medicine with you in case you are stopped. I always make sure I have medical insurance that will cover my diabetes, make sure the people I travel with are aware of my condition and how to help me if I need them to. If you are going to a non-English speaking country it may be helpful to learn some useful phrases in case you need medical assistance. Also it could help to research where the nearest medical center or hospital is.
All of these things are things I tend to do when I go away but everyone is different, but if you are planning a trip just make sure you keep yourself safe and of course enjoy it!
