Squeak, you have to be selective about when you drink your water. I NEVER get a drink when I'm going to see a movie. Those days are OVER!
And I'm lucky to be home all day (for the most part), because in the morning with 3 cups of coffee and about 3 waters, I'm peeing CONSTANTLY!
I think your bladder will start to adjust in a couple of weeks. But you still have to watch when you're drinking...
I find now that I'm addicted to water I have to have one or two glasses as soon as I get up in the morning. I really notice the dehydration from the previous night's sleep. Maybe if you do that, you can get some of your peeing over with before you go to work.

Keep it up with the water, though! Your body will thank you!
Ummm... re: my weekend goal? It's screwed. Totally screwed. I'm going to get a pedometre tomorrow (thank you, Lidian!) and start afresh. Ideally, I need to go to a fat farm for 6 months.
