I wouldn't jump strait to maintanance. Go ahead and start adding back in carbs and going through OWL so you know what your level of carb tolerence is. Going strait to maintanance and guessing could make the weight come back. Since you are so close you could try adding 10g of carbs per day each week instead of 5, then when you stop losing, or gain just a bit, cut back by 5g until you hit goal. Remember too if you start eating more carbs you may retain a little more water weight as a reaction, so stick with the new carb number for at least a week to be sure it's high and it's not just water.

As close as you are the weight loss will slow, don't feel discouraged. Atkins states the slower you lose those last few pounds the more likely they are to stay off. OWL also adds food in slowly and teaches you how your body reacts to certain foods so you can keep this WOE up for life
