That is an "old wives's Tale" (not that you are old.)
Drinking water will not lower glucose levels. If you are at a high enough blood sugar level, you will be "spilling glucose" into your urine, and you need to drink water to counter that. You are then responding to the thirst that the imbalance in your water levels (osmotic balance) causes. Drinking by itself (when you are not thirsty) does nothing!
Drink when you are thirsty and you will be fine.
Actually, it's almost impossible to drink too much or too little, since your body has wonderful mechanisms to control thirst and body "osmotic pressure."
You can control your thirst by doing things like taking in salt, but your body will always push/pull your fluid levels into balance.
