when is your body done loosing weight?

Options
I am sitting still at the same weight for a month, before then I was steadily loosing weight at a rate of averaging 1-2 a week. Right now my current weight is lower now than it has ever been in my adult life. But I feel I need to loose about 5-8lbs more to be at my true ideal weight and for what I want to look like. I ideally want to be in a comfortable size, I am currently in between clothing sizes, the ideal clothing size is tight but some fit.

When do you stop worrying about the scale going down and just enjoy maintenance but still eating healthy and remaining active.

I am getting frustrated with this last 5-8lbs.
