One month already!!!

Yesterday marked 1 month of my CALP experience. I cannot beleive that I have come this far on this programme. On other diets, I would have fallen off the band wagon 50 times already by now but on CALP I had gone off 3 times only to date. My first was at my inlaw's house and the 2nd & 3rd was during a recent 2-day office retreat. I notice that I have no difficulty following CALP when I am on my own but cave in when I am following other people's eating schedule. I know it was nobody's fault but my own. I should have been stronger and just say no. But often , I dont have the heart to dissapoint them when they have gone to so much trouble preparing food for me. hmmm.... i wonder how most of you out there deal with situations like this? I would appreciate your comments or sucess stories on this please. thanks!
