I hear ya! I know how tough it is! Hiding at the dark corner of where our good old lord can't see, we stuff our faces with chips and the precious left over food from the fridge! We are fighting against the weakness of human nature through our bodies :oP
I believe most fasters have been through this stage, I did, I really wondered if I could ever fast for more than 7 days, and I felt really bad for myself when I couldn't do it, while seeing other people doing it without too much troubles.
Cheer up! Don't get depressed for it, try different things that can keep you on the track, give your food away so you wont have any temptation at home! Or finish it so that you wont be thinking about them once they are done. Just remember you are doing your best to improve your health, this is very positive and encouraging, we should embrace this, don't judge yourself, we should help your body to get this message and be cooperative with your mind! Picture the kind of vitality and great health after fasting you will have everytime you try to eat.
I'm doing my fasting fairly soon, please take care!
