I think it's okay to think outside of the box. Eating typical lunch or dinner food for breakfast is a great idea, IMO,
IF it works for you. If not, well then, that's okay too. Chicken is loaded with protein. A great way to start the day. I very often eat my biggest meal at lunch time. Then it's kind of like a treat for me to have a bowl of oatmeal and an egg white omlette come DINNER time. We all have to find what works for ourselves.
Marsielle, I HATE those kind of days. You've already gotten some good suggestions. How about a nice, BIG cut up salad with lots of veggies and a can of tuna thrown in? Or go make yourself some homemade applesauce. Very easy and quick - and satisfying. A cup of SF hot chocolate? Hmmm, what else, let's see - oh, how about a nice veggie platter with a little hummus?
Also try drinking lots of water. MAybe you're really thirsty.
And if food is just not doing it for you today, why not try and take your mind off of food all together? Straighten up the house, organize your closets/drawers, take a walk, do a little shopping.
Hopefully tomorrow will be a better day.
