Spending more time in the library without money in your wallet/purse and arriving home too late to cook should solve some problems. In the short term. Mostly, I start to fantasise about food and end up going home to gorge. Still, my metabolism is starting to crash and I'm having to watch things more. I've started to comfort eat already, so if I want to fit into my clothes in a months time I shall have to calm it down a bit!
