You need a in bracelet. Medicalert is cheap or free if you can't afford it. Here's the reasons:
1 - they don't think about treating you as a diabetic, some of the meds or things they will use will be bad for you.
2 - When your out someone might take your wallet. Sometimes thieves pick on weak people and when you your passed out your a perfect target.
3 - You can pass out form something happening around you having nothing to do with diabetes.
With me I have passed out 3 time 2 times while I was leaving work, hitting the outside hot air in the desert. Having the bracelet is the smartest thing in the world, it's engraved with your condition and a control number so not everyone knows everything about you. But any medical professional can call a free number and get all your details meds, docs and stuff. They will even call your doc, and family. So they see the condition they know right off the back some things about you then once they call they know everything.
