Congratulations again! In 35 weeks! Oh my, you really are a success story...do post more about your weight loss so it will remain in one place for people to read.
There are a number of people in Dr. Westman's support group who remain around 20g TC and never more than 30 to maintain their loss. Their bodies just cannot handle more carbs without gaining and it is perfectly healthy to do so. Sounds like an excellent plan to find your CCL.
