Frozen Water Bottles

I'm so hungry right now. But I know I need to make sure that I make weight for nationals. So I have my water bottle...and once that's gone....that's it. No more until after weigh-in when we get to Boston at like 3:30 tomorrow afternoon. I get the feeling that today and tomorrow are going to blur together since we're leaving at 1 am tonight to go to Kansas City and then fly to Boston.
I froze my water bottle so I can't drink it as fast...but DAMN! I'm in a bad mood wanting food and not even having water to drink right now.
I'm at work for another 1 1/2...not doing anything cause there's nothing for me to do.....
Then I go to chem lab......and a mtg. at 6......then I pack and hopefully sleep so before we leave.
Cause quite honestly I'm not sure I can handle being at home and not walking into the kitchen and eating something...which means I either need to be busy or unconcious :-)
Ahh I'm going to be in a loverly cranky mood for a 4 hour drive!
