I have come to the conclusion that this old body does not like to have blood sugar levels below 100 and I get a shaky feeling when it gets to 97. In the 80's I feel really shaky so I don't let it get that low anymore, as I suffered from hypoglycemia some years ago, mostly due to stress in the home. I cured that problem with diet change and cutting down on the noise and disruptions at the time. Even the bird in my daughter's bird cage couldn't stand the noise, and it went into a corner and died. I turned down the TV and the phone ring. I am awake because I ate two delicious salads that were low calorie and need a snack which I am trying to avoid if I can. I also eat an excellent diet that is balanced and eliminates sugar and many carbs. All I can say is I am working on it. Dorisena
