If your blood sugar level is too low, eat some sugar (drink a reg. pop, for example). Wait for 15 minutes and then retest yourself. If you have glucose tablets, too, that is another option instead of pop or orange juice. Now, if your blood sugar is too high, take maybe 1 or 2 units of insulin, if you are on insulin. If you aren't, try eating some peanuts, corn chips...anything without sugar in it. Watch the signs. Do you get real sleepy when your sugar level is too high? Do you get excruciating headaches? At that point, you need to contact your doctor and see what he/she says to do.. . Good luck.
