This is a very large fear of mine but we've been lucky to have extra supplies in almost every T1D category. People seem to forget that most diabetic supplies in the US are gated by insurance who make it extremely difficult to create a small stash. We bring extra ( most that i had to cash pay for ) insulin, long acting , CGM's, multiple blood glucose monitors. We also recently were able to bring my sons old X2 with us on vacation. So we have backups for everything.
Also use facebook groups if your in a situation like OP is in. I could post on my local T1D group looking for long acting and could get 5-10 offers.
They also had a way to share friend codes in game. I don’t remember exactly what it was but there was a mechanism that had letters on a wall and combined with a few other things you could make out someone’s code.
What do you use then to make these decisions? If you use your eyes, app, nutrition label or Chatgpt, you would still have the same variables. You're still making the decision based on averages, and best guesses.
I meant more in a general way, like a piece of pizza is usually around X carbs. We have apps that make the guess a bit easier but it's almost always a guess. I was thinking could this look at a photo and know there's a sweet potato, a piece of chicken and some corn and give a basic idea.
Amazon pharmacy is probably one of the best interactions I’ve had with Amazon and pharmacies in general. We moved everything we could to it. The support has been great. Get things quickly all the information is right up front.
