yeah, i’ve been told that as well. however, i haven’t really had issues with it since i always make sure to eat beforehand/during and/or after.
i’ll be honest: i drink a lot, and if anything my blood sugars edge more toward the high range. while its not ideal, and while i know it does sound bad, i’d much prefer to be a little bit more high with my sugars when i drink just in case my sugars drop unexpectedly.
another thing that helps is the Dexcom, a continuous blood glucose monitor that checks my blood sugars every 5 minutes, and documents the trends. its great when i don’t have the time to check my blood sugar via finger pricking, and can alert me if my sugars are going up/down.
