I am starting my fourth week and have lost 21 lbs. I also have a problem with feeling full. I try to limit my portions and stop when the plate is empty. I drink 2 32 oz. bottles of Water a day plus my 12 oz coffee and 16 oz of milk. At this stage I think I should only be eating 1/4 to 1/2 cup per meal yet I don't feel full. I try not to drink at least 15 min. before eating and 15 min. after eating. I have been 21 lbs down now for 4 days and the scale isn't going down. What do I do?
