Is drinking water at Suhoor sufficient for fasting the six days of Shawwal?

It is sufficient for the suhoor to only drink water, even though it is better to eat something. Its virtue is achieved by drinking water, and its virtue is perfected by eating; as the Prophet, peace and blessings be upon him, said: "The suhoor is a blessed meal, so do not abandon it, even if one of you only takes a sip of water. Indeed, Allah Almighty and His angels send blessings upon those who partake in thehoor."
