That is so funny that you are craving Pop Tarts too. At least they do have a decent amount of vitamins in them! Soy also turned me off big time by the 9th or 10th week. I wouldn't switch fibers if you are feeling good about what you are taking. I began to feel sick everytime I drank the Citrucel, so I knew it had to go. I put that in there just in case you were on Citrucel, but I think acacia is a lot like Benefiber.
I had my baby girl on Dec. 11, 2003. I was induced because the baby got so big that the doctor was afraid I would have to have a C-section if I waited any longer. I am very short and small boned. Despite my lack of weight gain in the beginning, I gained 50 lbs! I could barely drag myself around by the end. Eventually the ibs came back and helped me lose it all.
You sound like you are on the right road and I predict that you will be eating like a football player this summer. Enjoy!
