Hi there,
Technically, yes- you are supposed to eat all your daily points. If you are having trouble getting to your daily target, you could try adding something that's higher in points to your diet, like cheese in your sandwich or salad, or some nuts.
That being said, I don't believe you should eat until you're sick. There has been the odd day that I've been 1-3 points under, and the odd day when I've been 1-3 points over. As long as you're usually hitting your daily target, it shouldn't make too much of a difference. I once ate a bunch of food at the end of the day because I hadn't met my target and made myself so sick that I threw up! Not fun!
Good luck
