Seems that there are different viewpoints on carb-loading before a race, and I found this in an active.com article located here:

The no-depletion method
Fortunately, later research showed that you can increase glycogen storage significantly without first depleting it. A newer carbo-loading protocol based on this research calls for athletes to eat a normal diet of 55 to 60 percent carbohydrate until three days before racing, and then switch to a 70 percent carbohydrate diet for the final three days, plus race morning.
As for exercise, this tamer carbo-loading method suggests one last longer workout (but not an exhaustive workout) done a week from race day followed by increasingly shorter workouts throughout race week. It’s simple, it’s non-excruciating, and it works. Admittedly, some scientists and athletes still swear that the Ahlborg protocol is more effective, but if it is, the difference is slight and probably not worth the suffering and inherent risks.
Note that you should increase your carbohydrate intake not by increasing your total caloric intake, but rather by reducing fat and protein intake in an amount that equals or slightly exceeds the amount of carbohydrate you add. Combining less training with more total calories could result in last-minute weight gain that will only slow you down.
Be aware, too, that for every gram of carbohydrate the body stores, it also stores 3 to 5 grams of water, which leads many athletes to feel bloated by the end of a three-day loading period. The water weight will be long gone by the time you finish your race, however.
Basically, from the article, they recommend the following procedure. I think i’m just about following this, I started eating more carbs today, I just have to realize that I have to maintain my overall calories and not take in more calories just because of the carbs (so I don’t gain back the weight I worked so hard to lose)
Here is the detail of the no-depletion method:
The No-Depletion
Carbo-Loading Method1. Perform a long workout (but not an exhaustive workout) one week before race day.
2. Eat normally (55-60% carbohydrate) until three days before a longer race.
3. Eat a high-carb diet (70%) the final three days before racing while training very lightly.
We’ll see how this works for the half-marathon with the intention of using it for the steamtown marathon in the fall.
