Hi, Sunshine!
It is not uncommon to eat more carbs while on vacation.
As you recall from Doug's book, overt "sugars" are only a small part of the standard American diet.
There are those "hidden sugars" in breads, dressings, etc..
When we eat more carbs than we should, it can cause cravings, false hunger,
and a number of other things common to a high-carb lifestyle.
The best way to deal with this is just get back on track.
Eat less than 20 net carbs per day, measure your portions and eat NO more than you need!
Here's a link to Doug's 15 Minute Rule to help you adjust your portion sizes:

You just have to commit to doing it and put forth the effort.
If you do, it WILL work!
