Sally has said exactly what I would have done, especially re weighing. It is hard to begin with, I used to weigh morning AND evening and sometimes in between at one point but it really does affect how your day pans out. If the scales showed a loss, even a tiny one, it would make me a bit complacent and maybe tiny bites of this and that might not get counted, or more likely, portions sizes of free foods would be just a little larger and superspeed foods a little less. Obviously that makes a difference, it might not seem it at the time, easy to convince yourself there was no harm but it could be enough to make a loss into a STS, or even a gain, which is very disheartening.
By not weighing from one Friday to the next, I don't know what is happening so I'm far more likely to be 'extra' good, just in case, if you see what I mean. It is so much better, yes, it took a while to get used to and sometimes I'm still tempted to go and retrieve the scales from the cupboard just to check but I've resisted and am slowly getting used to it.
Try it tomorrow.... and then next week, see if you can at least go for longer stretches and after a while, you'll find its not bothering you. My other suggestion is to keep a big glass of water by your bed (or a bottle) and first thing, drink some, before you even get up to go to the loo, then tell yourself that its not worth weighing as that glassful will have made you weigh heavier. It works for me and of course, extra fluid is always a good thing.
Good luck with it and I'm sure your work in the gym and on food, WILL pay off, it has to! xx
