Awesome and keep going! I hosted a Thanksgiving party being on 800 cal diet. It was tough! I might have had too much protein/turkey :/
To get rid of food smell, try eucalyptus oil, it really overpowers all other smells and is calming. And every time I thought of food I always had a bottle or glass of Water and kept sipping on it. For headache try just tiny piece of darkest chocolate to open up your veins.
Good luck!
