I had the same problem for about a month when I did LT last year. I used the fiberclear throughout, but I found that the flapjacks helped a lot, they seemed to have a mild laxative effect. Maybe you should give them a try.
Judging from the magazine, you also have to count calories. There are some lovely recipes in the magazine. I'd love to do the Rosemary Conley diet but there are no classes near me.
I notice that sometimes the weight is different if you place the scales on different areas - even on the same type of surface. So I dont worry too much if it goes up or down 1-2lbs. More than that and its time to do something about it.
