At least once a day my hands get shaky, and I am very angry with a feeling that I NEED to eat right away. Sometimes my lips tingle and start to go numb, and I get lightheaded with slightly blurred vision. I feel nauseous, sleepy, just plain weird. My sister checked my sugar one day an hour after a snack and half a mountain dew, and my sugar was only 89. I know this is not a really low level, but my face felt kinda numb and I was STARVING! Any suggestions of what this might be?
