@Nicola M your advice is fantastic (the best so far
). I have a few additions based on my experience.
The advice I was given (and have always followed) is to take
at least twice as much of everything than you think you need.
This includes spare insulin pens if you use reusable ones and batteries for the glucose meter (unless it is rechargeable) as well as needles, test strips, lancets, etc.
Take care with using "holiday" fridges. I have read too many stories of fridges that are too cold and freeze insulin. I prefer to stick with Frio wallet when away for less than a month, As you say, insulin is fine out f the fridge provided it is not left in direct sunlight,
My additional advice (from personal experience) is to make sure you have hypo treatments with you in your seat not the overhead locker in case you experience a hypo when the seatbelt sign is on.
It is best to request this from your diabetes clinic as GPs tend to charge for them.
In twenty years of travelling with Type 1 and hunrdeds of flights, I have only had to show my letter once (it is now looking very tatty) but I take it just in case.
Some people also take a copy of their prescription. However, mine it now electronic so I don't have anything to show ... and never needed to.
Personally, I do not like to spread personal information about my medical conditions. I have never been on a cruise but have never told tour leaders on adventure holidays. As
@Dudette1 is going with her husband, I am sure he will be able to explain to the crew if there is an issue.
This is down to your personal preference.
Nicola - apologies if it looks as if I have decimated your advice. This was not my intention. As I said at the start, your advice is great and I just wanted to expand upon it.
@Dudette1 congratulations on your upcoming nuptials. As others have said, diabetes should not affect your enjoyment although it may go a little awry due to the change of routine.
