A friend's mother ate nothing but clams for six months. Morning, noon, and night, nothing but clams. 'I don't know what it is - I can't seem to get enough of them' she told her son. He shakes his head, but I understand. I eat nothing but broccoli for a month, then yogurt for six days, then (for one glorious week) lamb chops. One day I roasted a chicken and had seven chicken sandwiches before nightfall. If I like something, I like it a lot. Just one doesn't cut it. I don't know what it is I can't get enough of.
