After eating stuff high in sugar, i begin to get a vague headache and i feel out of it. blood sugar normal. sometimes severe fatigue with it.

Symptoms after eatin: high sugar food. A single glucose test only reflects one moment in time. Please see your doc who may order an A1c test which measures about 4 months of the way your body processes glucose. He/she may also order a glucose tolerance test and, of course, examine you for other possibilities. Peace and good health. Consider stevia rather than sugar or chemical sweeteners no matter what.
