I plan to travel to California and stay more than one month.
I'm an insulin-dependant Diabetic. I am able to bring enough insulin with me to last the entire duration of my visit, but the issue is I'd like to hire a car and drive around the state. This means no access to a fridge on the days I'll be driving (and potentially the nights too, depending on where I stay in between driving days) which means I'll have to store the insulin in a cooling wallet.
Unfortunately in the cooling wallet the maximum lifespan of the insulin is four weeks (in a fridge it's months). Meaning no matter how much I take with me, the most I'm going to be able to use is four weeks' worth, before needing to obtain a 'fresh' supply.
So, what are my options for obtaining insulin as a foreign tourist in California? I'm a UK citizen if that's relevant, though I doubt it. I have travel insurance for the US but as far as I know it doesn't cover trips to the doctor for anything non-emergency, if indeed a doctor's prescription will be required.
Can it be done? Or am I basically limited to either staying less than a month, or ditching the driving plan? I really, really don't want to give up on this plan :-)
