Good luck, it is a great diet to do and the results can be phenomenal. There are many people on here who are in for the long haul too, myself for one. I shall be hovering round for at least 6 months. Luckily it is a really nice site, and I find when I am feeling a bit weak if I pop on here I usually distract myself for as long as it takes.
If you haven't done the diet before the first few days can be a bit of a trial but stick with it, drink loads of water and have some pain killers on hand (for headaches from carb withdrawal).
Good luck.
