Does Readi-Cat 2 Berry Smoothie contain carbs or sugar? How much?

You need to call either the Dr who ordered the test or the facility where you are having it done. They will give you instructions for what meds to take before hand, including insulin. Just be sure that they know you are diabetic. No worries! You are not the first diabetic they have had nor will you be the last. Usually once you are scheduled, they have a nurse call you to go over all of the instructions for how to prep for the test and she should be able to tell you what to do but just in case they dont have someone like this calling first, you can certainly call either your Dr who ordered it, or the facility that is doing the test. If they tell you not to use anything, dont worry. They will have the ability to treat you in the event that your sugar gets too high or low. They usually give you a prep to clean you out and usually have you to not eat or drink after midnight the night before if you are scheduled in the morning (which you should be because you are diabetic!) and they will let you know what all medications to take prior to the procedure. Good Luck!
