My first major craving was for anything salty. At that point I was aiming for the healthy diet, but I'd add salt to everything and could scarf down pretzels like nobody's business. One evening I gave in and bought Top Ramen -- something I would never normally eat.
Maybe at about 7 weeks I transitioned to carb cravings. I have been living off of bagels and feel so good right now after having eaten an entire plate of pad thai (while shoving the vegetables around).
Have you had the same cravings? What's up next?
