Have you looked up the carb content?
At the end f the day, the only way you will know, should you want to try it enough, is to wait until a decent while after you last ate, and test (the waiting is to try to ensure you have very little else influencing the readings). After the initial test, drink then test again in an hour and half hourly or hourly ongoing until your levels come down again to where they started.
That will inform you.
