Going On A Cruise--Doing A Quick Diet

I am heading on a cruise on Saturday. No, I am not packed, and I am still overweight. I will start packing in a few minutes, and I did go on a quick diet The four-day diet. I am on day two. Unfortunately, my fourth day will be the day that I am flying to my port. But, oh well. Supposed to lose 5-10 pounds from this. That would be great. You eat healthy food, but the diet claims it is not nutritionally sound (probably too few calories) so you are not supposed to do it more than once a month. But to me, that is doable. For the first time, I really feel psyched again about losing weight.
