Stopping drinking isn't in itself necessarily going to lose us weight. To be honest you are probably much more hydrated than you were when drinking, so I bet a lot of your gain was that. I know we can count up the calories we'd have drunk and say that logically we're having that many less calories, but our bodies probably had to work harder just to survive back then.
You say there is no exercise. Is there a way you could add some in? It's good for our mood to do some exercise as much as our weight. It doesn't necessarily need to be hardcore - maybe some cycling, or dancing like a mad thing to your favourite music as you do the housework, or hula hooping, or brisk walk round the block.
To be honest your body is likely still getting over the shock in your habits. Give it time. One thing at a time.
