I find eating slower helps. I've really started to hate that 'really full' feeling. I like to be satisfied, but anything past that is uncomfortable.
So what i do is eat as slowly as i can (whatever slowish pace is reasonable for you), and drink water in between bites.
Removing the food after you feel full is also something i do. Whether that is taking your plate to the kitchen, throwing out the food, or putting your napkin on your plate. Which ever will stop you from taking more food. Oh and if you're eating family style, just put what you think you can eat on your plate, and then only take more if you are still hungry.
When other little girls wanted to be ballet dancers I kind of wanted to be a vampire.
