Best Answer:you have reactive hypoglycemia
your body overeacts to fast-absorbed sugar
This causes an excessive release of insulin, which decreases your blood sugar by removing it from the blood and sending it to the cells.
But since the insulin is excessive, too much blood sugar is removed from the blodd and none is left for the brain. Then you have low blood sugar and you feel lethargic, confused, weak and have blurred vision.
In order to increase your blood sugar, your body releases adrenalin.
This causes shakiness, sweating, a feeling of panic.
When this happens you should eat a protein and a complex carbs, like bread and cheese.
Eating simple sugars to raise your blood sugar is the worst thing as it will rebound.
You should avoid simple sugars (expecially candies) eat sweets only after your meal and choose small portions of less sugary desserts. You should expecially avoid sweets and sugars on an empty stomach, sweets or even fruits at breakfast, alcohol and should have meals that contain enough fat (no low fat meals for you) and a good proportion of proteins and complex carbs.
