Hi Blue, Im going through the same thing. Had a terrible weekend. Went for a carvery, and I started off really well only having the meat, then I went the whole hog and had potatoes, veg & yorkshire pud with gravy. And if that werent bad enough then I went to a kids bday party & had 2 slices of pizza, & came home & had 2 bottles of wine. Once I fall off the wagon, I fall hard! So I back at square one today, trying to get back into ketosis. The only bit of advice I would give is that its really not worth having to start all over again for a slice of pizza or bottle of wine! Just read up on the list of foods that keep yyou in ketosis & stick to them. I really wish I had. Good Luck & happy bday for the 17th xxx
