Everyday first thing in the morning and then several times during the day. It helps keep me on track. But I only officially count it once a week.

Once I get my new scales, I will start keeping track of food and weight. That way I can compare and see what I might be doing wrong if I have an unexpected gain.

When dieting I try to only weigh myself once a week, unless TOM is here then I do not weigh til after because I always weigh about 5 pounds more.

Thanks for all the responses! I've been weighing myself every day (and yes, sometimes multiple times) just to see it... though I'm only recording once a week. I'm just too impatient to wait a whole week!
