I think a lot of people go through this. I'm in the same boat.
My clothes look like they belong to someone else - my jeans would just drop to the floor if i didn't belt them right up.
I have noticed that I'm starting to gorge on chocs and biscuits now (at 14-month mark).
Is there anything you can come at, food-wise? If so, go for it. I realise that this isn't a long-term solution, but try to treat yourself with an 'indulgence' if you can.
You need a lot of strength and stamina to get through this, so perhaps also try to think of yourself as an athlete in training. This might help you to eat something even when you don't feel like it.
