I have diabetis for the last 8 years. I do not take any medicine since I jog for 5 kms daily, 1 hour work out in gym and controlled food habits. Hence my sugar level used to be around 145 to 170 range. But for the last few days I could not exercise much and now when I checked post lunch my sugar level shows 370 !!! let me know is it time for me start taking insulin tablets apart from workouts...
