Are these foods okay? what happens if you cheat during the consolidation phase?

Hi! I just started the Dukan diet last week and it is working amazingly! I did cheat this past weekend (in cruise phase), it was my cousin's 21st birthday, and then I was right back on the band wagon and lost the one pound I gained thanks probably to doing a pp day right away. Anyway I was just curious, I have a vacation that I am losing the weight for but it lands towards the end of the consolidation phase and I was wondering if (or when) I cheat on the vacation do I start up again on the cruise phase or do I keep on with the consolidation phase? HELP! Also does anyone know if you can eat the following on the cruise and consolidation phases: swiss miss sugar free hot chocolate, protein shakes, sugar free jello pudding cups, or sugar free ice cream? Thanks a bunch!!
