Yep, I would increase the food intake before trying anything else. Focus for a few days or even a week if necessary on getting ALL of your base points in - no going to bed with 10 left!

If you feel full, have some nuts (4 points for an ounce), a spoonful of PB, or something similarly high-points while also not bulky. Forget "low fat" versions of foods you eat until you up your intake.
This is vitally important to the program - EAT YOUR POINTS!
WW gave them to you for a reason. People tend to get stuck in the "this is a diet, I must eat as little as possible" mindset, which becomes counter productive and actually harms us in the long run. Boost your food intake for a week or two and see what happens. Once you have committed to eating your daily points without falter, you can look at adding in some FPs as slow as you feel comfortable with - but it is important that you get your intake up!
