Weigh Ins

I've been weighing every day and the number keeps going down. That makes sense, since I'm exercising and eating 1200-1500 calories per day. After tomorrow I'm going to scale back to two weekly weigh ins. Every day is too much, and once I stabilize it's a potential source of frustration.

This morning was 214.7. That's 4.2 pounds less from day 1, four days ago.

I'm thinking about next month. A scale will not be as handy. I am not traveling with my Wii balance board. Should I buy a scale so that I keep up the weekly weigh ins or just go through the month without stepping on the scale? I know I'll be losing, because I'll be keeping up the program.

Do I need the weigh-ins to keep me honest? Or can I substitute the tape measure for the weigh ins.?
