Okay, the boy is on his way to the movies, the critters are taken care of, etc, so I can take a little computer time...
I've been doing 1800 and 2000 cals for a long time, and see that my weight loss has slowed most weeks to under a pound a week. So, starting today, I'm switching my calorie counts to 1600 most days, and 1800 on weight lifting days. I've decided to go back to full body lifting workouts for a while, because I think it may help if I don't have to drink the post-workout shake five days a week, and this way my food calories stay the same (1600). All I have to do to get the 1800 is drop one cup of tea and have my post-workout protein shake.
So far today, I'm right on track with eating and water drinking. I am really going to try and stay focused and on-plan for this challenge. Those little spoonfuls of peanut butter or a taste of this or that really add up! I'm tracking every bite and drink on The Daily Plate site.
Sgirl and Yoyoma, thank you for the support and ideas for getting off the sugar/milk with my tea. I was a little surprised to hear that others on this list had tea with milk and sugar. Outside of my family, I've never met anyone who didn't think this was an odd way to drink tea.
Retiredone, congrats on your weight loss...you are off to a great start!
Freethetoys, as FB said, we all just weigh in whenever we feel like it.
FB, as always, you are the weight loss "boss of me"! You keep me motivated!
Fakefrowns and Lifechange, welcome to the CD challenge, and good luck!
Wow, that's long...sorry guys, I need an editor!
ETA: Yoyoma, you posted at the same time I did. For the ticker, what I do is just track the lowest weight I've hit on the scale, because my weight also fluctuates day to day. For me, it works to track the low weights, because if I'm doing a challenge like this, and I see my goal number on the scale, I'm friggin' counting it!

At home, I track my average weight loss, using a week of daily weigh-ins, adding them together, and dividing by 7. That gives me a clearer picture of my weight loss trend from week to week. What you track on the ticker is up to you, but it motivates me to use it for tracking my lowest hits on the scale.
