This is me lately. Really early on I had a few symptoms but they've largely went away - which is a little disconcerting sometimes, but I remind myself that I didn't have any real symptoms with DS either. I could eat all friggin' day though. I have dinner and then I need a snack before bedtime, which I normally wouldn't do at all.
I hear ya with the eating all the time! I've been eating almost every hour or so, just something to keep my stomach from getting that empty nausea feeling. I went to see the Hobbit this weekend, and there's a scene where Bilbo and the dwarves are all eating this huge feast and everything looked so good! I decided what I'm craving is old-english peasant fare......lots of breads and cheeses and yummy sausages and fresh garden tomatoes! That's what they all were eating, and I was practically drooling! :)
