Anytime you play with your blood sugar levels, headaches are a possibility, whether it be eating sugary foods or injecting insulin itself. Are you sure you're getting enough carbs?

i did 8IU followed by 75g of carbs from dextrose (1/3 cup) and 5g of carbs from my protein shake. 1 hour later i had 1 cup of rice with chicken. when i felt the headache coming on i drank a pepsi.
