First, you're halfway to your goal! Wow! Congratulations, that's a real accomplishment.
Sounds like you're sticking to your points. You may already have this covered, but making sure you get enough sleep can have a big impact on your weight loss. Also, getting rid of diet drinks can help you reduce your feelings of hunger, which can help you shave off a few points here and there.
Lastly, if you can fit it into your points budget, there is a growing amount of evidence that avoiding carbs until at least noon can have a big impact as well, even if it's just a few days a week. So you might try think about trying two eggs or a small piece of cheese for breakfast if you can get it to fit into your point limit.
In any case, good luck!
