For the water--I joined the water drinking challenge last week--and it has been a challenge. I have a small refrigerator in my classroom--and I keep bottled water there. When I empty one bottle, I grab another. I carry it around the room with me.

Bathroom breaks have been a challenge, but fortunately there is a bathroom very near my room and I've about trained my bladder for between class trips. It is getting better, I'm making fewer trips every day.
