EllieG - hope you enjoy your weekend away. littlemisssensible's right - just go with the flow, eat healthy bits if you can, but don't obsess about it, and accept that some days you'll eat more, some less. And all that going to the gym will be speeding up your metabolism, so that you're working off your food quicker.
Sue - so frustrating for you. I would take bets on it being the scales that are having the fluctuations, and not you - and very annoying to have speaking ones.
I've weighed, and have, I think, lost half a pound. I did overdo it a bit at book club yesterday, so am trying to rein myself back in again now.
