Unrequested advice: drink your bottle, pass security with it, refill your bottle at any fountain, bar, toilet after security.

If you're dehydrated tell a hostess, free water will be provided (costs them a lot less than being sued).

I just empty my water bottle before the security line. Take the top off when it goes through the X-ray and fill it up after.
