I'm not sure why but I don't think I was ever *really* hungry, even in the first few days. I was drinking plenty of water, had a large glass that never left my side and I kept topped up, I think that helped a lot with the feelings of hunger. Now I don't feel hungry at all with or without water, it really does get so much easier as the first days pass so you'll be soooo glad that you've stuck it out by the end of your first week.
I was thinking about food a lot, but that was more out of boredom, when I started I knew that my biggest enemy would be myself so totally expected to have those thoughts/urges and it kinda made it easier dealing with them when they arrived as I could be a bit detached about it.
At this point the only food I look/think about is the stuff I'm going to eat when I finish, and I'm actually trying to take the time I have now without the pressure of food to look at sorting out a healthy diet in the future. Fresher, simpler, and better quality I think is what I'm going to aim for.
