Up to what time may I drink and eat prior to surgery?

Many studies done in the early 1990’s have shown that clear liquids empty rapidly from the stomach and need not be held for the usual eight hours prior to surgery. The current fluid and solid food policy is as follows:
No solid food after midnight, the day of surgery.
Unlimited amounts of only water is allowed up to two hours before arrival at Riverside.
Juices, soda pop, coffee and all other clear liquids are not allowed.
There is no volume limitation to the amount of liquids.
If you are called by the operating room for an earlier than scheduled arrival, you can have your water only up to the time of the call.
