OK, I will come straight to all your South Beach experts for this one.

A friend of mine has recently started South Beach, still in induction period. She really doesn't have much to lose, I think she has just put on a few pounds lately and is trying to turn the tide before it gets to late.

But her concern is about the rock-like feeling in her stomach she gets often after she eats.

Does anyone have a clue to what or why she is getting this? As far as I know she is follow induction to the letter. Any ideas would be very helpful.
