Hi Paula,
I was the same first time I did LL. I knew that the vegetable soup didn't agree with me, but didn't know about the chicken soup until I did LL again.
Could be one of the foodpacks?? Or, I suffer from IBS and have found that taking psyllium husk powder everyday helps loads.....as it bulks everything out.
Hope this helps, it used to make me feel so wiped out and empty, and was a real problem for me before.
Lumpy xx
