Start with Cold ez or other Zinc med. They work for me. Also hit you immune with Airbonrne for massive vitamin C and B. Hope you nip it in the bud. With the weather you have been having, I know the big day can't arrive too soon! On a side note, I kind of liked getting paired for dinner with couples. On our first cruise we had 4 couples (including a gay couple) all celebrating our anniversaries. They were all awesome, we had a blast together. We spent a good part of our evenings together at shows and games and such.
