More hugs for Buckner...

With your busy work schedule I would recommend eating a bigger meal between jobs around 3 PM and then after you finish the 2nd job at 10 PM try something lighter like a power bar or a salad, something with less carbs etc.
How many days of the week is your schedule like this? If you have a weekend off then I would recommend eating healthy at the regular times then and fitting in more exercise then if you can to help balance out your work days.
