Tastes like coke

Today I had my blood glucose test. I had to drink this cola an hour before being stuck with a needle. A friend of mine told me to boost up on proteins (namely eggs) before my test. I am slightly allergic to eggs but forced myself to eat two of them with my "coke." I got to the doctor's office and they took me to the back. The nurse stuck me and took about 5 tubes of blood. I really hope I don't have gestational diabetes. Life is already difficult enough without a modified diet.
