Why do I weigh less after work than in the morning?

I weigh myself every day. I always weigh myself nude, post bm, right after I wake up. The past week or so, I've weighed myself after work as well. My weight is usually 1-1.5 lb LOWER after the day is through. I know this is just water weight that is fluctuation, but I'm curious why this would be, as I ALWAYS hear that you should weigh yourself first thing in the morning, post poop! Ideas, anyone? Note: I'm an Admin Assistant. I don't work a physical job that would explain this as water weight loss from sweating....
