I started weight watchers in November, at first I 'done good' and lost 1/2 lb a week, then christmas happened, and now despite all my best efforts I'm still heavier than I was before I started

I reckon to have a healthy diet anyway apart from the alcohol - but I never do breakfast, never have. Now, my question - I keep reading that eating a healthy breakfast helps lose weight. BUT since I've never eaten it before, won't I just be consuming more calories if I add a breakfast? I dont snack, and have either a couple of sarnies or a pasta salad or veggie soup for lunch - all homemade. Any thoughts folks?
And Maria - a little more info on the diet????
