I'm not sure about the details of your situation, but it did occur to me that if you're physically uncomfortable after eating, a small unfill might help. For me, I have found that I need to strike a balance between good restriction and still being able to eat. If I can hardly eat anything, I get so frustrated that I want to binge on ice cream (which WILL go down!).
Other than that, my get-back-on-track, back-to-basics regimen includes:
* Drinking a Protein shake for Breakfast (I have trouble with solid food in the morning)
* Having a small, healthy mid-morning and mid-afternoon snack
* Bringing a healthy lunch with me to work so I'm not tempted to go out to fast food (which is my kryptonite)
* Focusing on "superfoods" (From "SuperFoods Rx" by Steven G. Pratt). I couldn't possibly eat as much of this healthy stuff as he suggests each day, so I figure there's less room for junk.
* Eating at least 70 grams of protein per day
* Drinking plenty of Water
* Taking a daily chewable adult multi Vitamin and Calcium supplement
* Exercise, especially strength training (this is a miracle worker for my mood and motivation, as well as weight loss). If you can't get to a gym, walk around the block, do sit-ups and wall push-ups at home.
* Journaling -- write about your feelings, maybe consider a support group or therapy. It could help.
Best of luck to you.
