Query: sits in stomach like a rock

Like other CLIF bars, they taste ok at first and then have a weird aftertaste like you ate something too rich, too filling. Then they sit in your stomach like a rock. I realize they're trying to make their bars more like granola cookies, but you can't have it both ways. Besides I don't know if these bars work because they are so rich, they're too granolaly.
