I try to limit myself to one cup of tea in the morning, which I finish about 1.5-2 hours before I start the test. I really don't want the need for a bathroom break to be my downfall!
The only thing I'm going to pay attention to is limiting my coffee intake in the morning. The last thing I want is to pee my pants during the first section. After the test is over I will be enjoying some illicit substances.
I think I did really well, so I dumped everything in the garbage this morning. I get free printing, so I can just reprint my materials if I actually do need to retake. And I didn't have much use for used tests/practice sets anyway.
