.. with insulin pens.. I've recently been diagnosed as needing to take insulin. At the moment, I'm on a medium dose and only taking it once a day.. But I'm traveling next week and need to keep extra pens with me. I'll be on a plane for many hours so the extra pens will need to be refrigerated. Once I get to my destination, I'll have a room fridge so storing there isn't a worry. What do you guys recommend for chilled long term traveling? Thanks!
