i bought my first set of scales in yrs a couple of months ago, and the first week i did mess about, weighing myself at different times of the day, dressed, in pjs, etc. but now i just pull them out every week to 10 days or so. my weight loss has slowed right down, so theres no point doing it any more. im glad i bought them cos i geta better idea weighing myself on the same set of scales, rather than doing it on everyone elses.
