Making a concentrated effort to eat smaller portions and less of them takes a long time and is not the most fun thing ever. On the other hand, it works. I had one serving for dinner last night and did not feel the need for a second. If I'm eating and I realize I'm full before my plate is empty, I stop anyways.
The fast food cravings pretty much quit as soon as I got the grease out of my system, then realized that any time I reintroduced it would make my stomach hurt. Normal food is more of a challenge, but I'm making progress.
