hiya,
I too won't make goal before holiday (although it seemed perfectly possible at the outset!). I go next Friday BUT I feel much better in myself for having lost what I have and I'm actually more determined to NOT totally lose the plot on holiday this time. I will have some extra treats and meals out, of course. That goes without saying. But I'm feeling very strong and determined not to just have a 15 day binge fest.
I'm more active, am already sleeping less, and am determined to carry on the extra walking while on holiday too.
