I'll pledge to stay off the scales all week. I don't hop on and off them all the time but I do have a bad habit of getting on them if I've eaten something I shouldn't to see if it's done any damage.
It's very counter-productive as, if I've gained, I go into 'I've blown it so I might as well pig out' mode and, if I haven't gained, I start thinking I can cheat!
So I'll stay off them till next Wednesday morning...
