By request, I have proof of the ugliness that is me in the PT sweats.
We've been without our bathroom/shower cadillacs for two weeks now. Broken sewer or water main.
There are plenty of 1 liter water bottles all over the place, so there is no excuse. I've been pretty good about getting down 3 of these a day.
Most of the time I don't use the Crystal Lite. Turns out they provide plenty of these packets in the DFAC (so I didn't have to bring any with me). But you have to remember to take some of the water out before adding the packet (this ICW nurse didn't heed that advice).
