Mine is mainly emotional eating... when I'm upset, or anxious, I eat secretly. I'll often spend vast amounts of money of junk good alone at the corner shop. For example, I once bought 2 big bags of crisps, 3 chocolate bars, 2 energy drinks, and 5 packs of sweets, all at one go.
I also overeat, especially when I'm not hungry, when I'm bored. It will be mainly when I'm sat in front of the TV, and I'm watching a good film or TV programme (NCIS is my favourite), and I just want something to do, so I eat.

It's a horrible, horrible disorder, and most of the time I wish I never had to eat food.
