Dropping carbs dramatically after living a life where you ate a normal/high amount of carbs is going to, most likely, make you miserable. If decreasing your carbs is of interest to you, do so slowly over time.
However with the gradual approach, you probably won't get that dramatic shedding of weight some people talk about. I don't care about that, personally, because I get enough satisfaction out of steady progress and make a game out of optimizing my diet with delicious yet low/moderate carb food.
