Welcome to early pregnancy! There is nothing like the urgent, intense, and attention-consuming EAT NOW feelings of pregnancy. I had it for the first 4 months, and if I tried to ignore it, I'd heave. Nothing has been like it before or since either.
Carry crackers in the car, in your purse, and keep them in your desk drawer! It won't last forever, but it can't be ignored now. Your body is using the calories to grow a baby. Imagine that!!
Cheers! Barbara
