Fits and Starts

Do any of you ever have extended periods of food cravings?  I'm on a grapes-and-cheese binge.  In fact, I'm sitting here right now with red grapes, sharp white cheddar and pecan Nut-Thins.  Rupert is asleep to my left, Riley is on my right getting little bites of cheese as I go.

I'm afraid I might run out of yarn on the sweater my cousin asked me to finish.  It doesn't quite add up that having to do all the ribbing in the main color would make that much difference, but it might.  I've frogged and re-cast-on the front trying to save yardage, but still may not get there.
