OK, then, electronic prescription: You add up how much you're going to need. For example, two a day times 90 days, 180 doses. You ask the doctor or whoever you see last (nurse replacement, whatever), to show you in your chart where your prescription is set for 180 doses or three 1 month refills or whatever so that you get 180 eaches. Just don't leave the room until someone shows you. And don't think that the pharmacy won't screw it up too. I would guestimate that the pharmacies here screw up something on 25-50% of the prescriptions, based on what I have personally seen. It might be small, like the wrong number of refills (very common), or it might be big like the wrong drug or telling the patient they really don't need that anyway. So, after you get your first prescription filled, you look at the label on the bottle and see how many refills you have left and if that jives with what you learned at the doctor's office. If it doesn't, you tell the pharmacist that's not how many refills you had and fix it now, before you leave the pharmacy (or pay them).
Type I Diabetes Mellitus (sometimes called Insulin Dependant Diabetes): Usually strikes teenagers. Something happened, probably a virus. Something else happened in response, probably your immune system making antibodies to the probably a virus. These antibodies somehow lock onto the cells in your pancreas that make insulin, more immune stuff happens, cells get killed, you have no insulin, your blood sugar goes through the roof, you die without insulin.
Type II Diabetes Mellitus (sometimes called Insulin Independant Diabetes, whether you take insulin or not): Usually strikes the elderly or older adults, especially the overweight. Your pancreas kicks out plenty of insulin. Insulin is a hormone molecule that tells the cells "DINNER TIME" and to start sucking up the food (sugar). The cells have receptors for the insulin molecule. In Type II DM, the cells don't have as many receptors or the receptors aren't working properly or for some other reason, the cells don't respond the same to insulin. Cells don't take in sugar, blood sugar goes way up, you could die. A blast of extra insulin makes the cells take up more sugar. Sort of like cranking up the volume of the message. Oral drugs can make them take up the sugar as well.
