An important thing to remember about hypos: The symptoms that you have (pounding heart, sweating, etc.) are from the adrenalin that is pumped into your system to warn you that your blood sugar is low. (The adrenalin also stimulates a release of sugar from your liver.) Even after you return your blood sugar to normal, the adrenaline may remain in your system causing symptoms. Thus, you don't need to keep eating as long as you feel symptoms. As soon as you become aware that you are having a hypo, you should eat two or three glucose tablets or candies high in glucose (also called dextrose), then test again in 10 minutes. If your BS is still low, take another tablet or candy and test again in 10 minutes (and keep doing that). Of course, if you test on your arm, there is a 10-20 minute delay in the results, so it is best to test on your fingers during a hypo. When I accidentally injected 30 units of R insulin into a vein, I ate a ton of food, but it wasn't necessary.
