Hi everyone.
Thanks for all the replies.
I tried the Frio wallet last year in Turkey. However, it needs to be left in the open air, for it to work properly. So, that means carrying it around when travelling; the moisture within the pack needs to evapoate.
I use Levemir and Novorapid; I could keep the Levemir refrigerated during the day, but I had to take it out with the Novo to use at night and found it difficult to keep them cool.
I have since found out from You-tube that there is a heat-stable insulin under development.
Apparently, diabetics in Africa have to bury their insulins to keep them cool - not everyone has access to a refrigerator...
My A1c had raised significantly following my holiday. Given the heat and the de-hydrating effect of high blood sugars, this did make the holiday a bit of an ordeal.
By the way, the same outcome took place following a fortnight in Lindos in 2008.
Thanks for advice on porcine insulin - I'll look into that.
