Have you figured out where you level of carbs is to maintain? Read level 2 & 3 of atkins...when you find that level you will have not problem maintaining you weight. My husband we raised up to 100 carb a day. He lost 2 lbs this month...so we are going to have to raise it a little more. Probably take him up to 120 and see what happens...hes already 8 lbs under his goal. SO even if he gains some of it back it will be fine. You are suposed to do it 5 or 10 carb at a time until you find your level.
AND CONGRATS ON REACHING YOU GOAL!!! THAT IS WONDEFUL!
