FBS should be done after an overnight fast. PPBS to be done 2 hours after a main meal (ideally lunch). You can take water while going for FBS. Take sugar medicine after the FBS test with your breakfast.

Hi., I can understand your concern.
8 hours fasting from the last meal of the days is enough to test FBS.
2 hours gap is enough for PPBS.
You can take water.
You should take sugar medicine, then only we can know the improvement.
