So the Doc said I cannot eat anything past 12 (I am still getting a meal in before I go to bed in an hour), but I have an appointment at 9 am and I asked him if I could at least have a protein drink because the think that messes up the accuracy of the bloodwork is the sugar in eating (hence why you can have coffee with no sugar) seeing as how my protein drink has only like 3-4 grams of sugar (if that), could I take it a couple hours before my bloodwork or should I just wait it out?
