W,
Okay. So you passed out and you are pretty sure it was low sugar. Let's suppose you are correct. In the meantime, you should avoid skipping meals and keep some juice in your car. I hope you are checking your glucose 4 times a day. Since your glucose runs low, perhaps you don't need any insulin at all? Some people can control diabetes with diet alone.
In the meantime, keep a log of your accuchecks so your physician can tailor your treatment to your eating habits.
