don't think there's any right or wrong!.. its what ever you comfy with! i get weighed at the doc's when i go for more tablets, but on occasion he gave me a 3 month prescription!.. a weekly chart on your signature "as i have done" worked for me.. i take a deep breath and creep on every sunday morning.. but saying that if ive had a couple of really good days i tend to have a sneaky peek! lol ..
think obsessing and scale hopping would be "chinese water torcher".. best try and get on with life..
just to say i once went to a different doctor and his scales showed a 7lb difference "and not in a good way".... he wanted to stop my xen, after a right struggle he finally went and fetched some other scales!!!... "oh how doctors don't like being proven wrong" .. :~/
