Nice effort and great progress you are making.
I'm wondering if sugar might be affecting you. I see on your fitday you have instant oatmeal . . . which tends to have a lot of sugar in it . . . as well as sugar for your coffee. Wonder if you're feeling little sugar crashes. Just a thought. My favorite oatmeal for good energy is McCann's Irish Steel Cut (slow-cooking). I add some ground flaxseeds and a banana at the end.
Add extra fruits and vegetables whenever you can. Since you've been losing weight, you might need to increase the fuel for your body (not the calories so much, but lots of good carbs in fruits and vegetables).
You could also experiment with eating something every 2 hours (such as an apple with a tbsp. of peanut butter). Also, make sure you are getting enough water and enough sleep.
Keep up the good work
