Oh, you thought I might have meant alcohol... I drink water at work. Most people would say I have a lot of water. A gallon in a 10 hour work-day is not uncommon.
There are a few drawbacks - I'm used to drinking quite a bit and I feel it when I don't, like over the weekends. Also, a two-hour meeting that doesn't have a convienient bathroom break in it somewhere can get interesting.
But drinking a lot has its positives as well, like when H.R. pulls your name for the random drug test. There was a conference room full of people downstairs sitting around drinking coffee, water, and tea until they thought they were ready for the test. Me? I just signed in, "tested" and was out in five minutes.
Really, I'm just trying to make the pregnant lady I live with not feel so bad for having to go to the bathroom often.
