For my parent's 50th anniversary we are all going on a cruise on the Mexican Riveria. I have never taken a cruise and I am worried as to what I will weigh when I return. I know I will blow my diet, and look forward to the wonderful food on board. Although, I will refrain from breads, chips, that sort of stuff. Advice is more than welcomed here. We leave January 4th. I am thinking I should lose some more weight before we leave.
