I like the cooking after the first week -- I'm like Sacred Silence in that I become a "feeder" when I am not an "eater".
But, my DH (who is doing South Beach and just announced that he lost 2.5 pounds to my 1.5) told me that when he gets half way to his goal -- and he thinks that'll be in two weeks -- that he is having a PIZZA NIGHT.
As, I have less to lose than he does and am not eating (SSing) and he is SB diet, and I will not be at my 1/2 way point in two weeks (I might be close). However, I have "cheat treat" lined up myself. My DD and I are planning to meet a friend of ours and her DD in London and we will all go to Harrold's for high tea. I plan on eating (in moderation), as it is a big treat for all of us (we have not seen each other in four years) and our little girls are only 10 and 11.
So, that may be a week without a loss -- but I will up my exercise and get right back on plan.
I find weekends the hardest as well - use to always be our treat time - takaway, bottle of wine - not so romantic anymore him tucking in to his favourite curry and me sucking a shake through a straw - lol
