Dieting is not as easy as it seems. For something that we do on a daily basis it can become so complicated to some of us. Then there are those of us that eating patterns change depending on how we feel. What's your physical illness of you don't mind me asking? I guess the best thing you could do is try to stick to the diet as much as possible and if you "cheat" then just continue on your path. Don't pay mind to what you have done and just get back on that path. Ultimately it's not the one or two food items that will cause a downfall. Its not easy to make those changes and change habits that we have used over years. Don't beat yourself up for having a tough time or having a few items that you're unable to have. Do you see a nutritionist? A nutritionist might be able to help with cravings and might be able to see where it is that your struggling and offer other options to make your diet more tolerable. Hope this helps.
