Dana- I'm sure yo have, but I'll ask anyway. Have you tried drinking water between every bite, it will help fill you up. Or making a smaller plate for yourself and then waiting an entire 10 minutes before deciding whether you are still hungry or not. Waiting 10 minutes, even if you've eaten entirely too fast, usually helps your brain catch up with your stomach in deciding "yes, I am full." And you will feel full even if you weren't when you started waiting, unless you are still hungry and if you are then chances are you are truly still hungry and not just shoveling food in your mouth too fast.
Gem- People don't respond to texts I send either. *sigh* It upsets me too because a text takes what, 10 seconds to answer? Assuming they've read it and everything.
