I think that you are doing great. You seem to have much better control over the binges and you are basically letting your system recover from some less than controlled eating. A sodium gain is par for the course and monitoring sodium and drinking water is bringing that out of your system.
However you look at it - clothes feeling looser and the scales showing a rapid loss have to be looked on as good signs. You may not think that it is worth getting excited about because of the recent gain - but I consider it well worth celebrating.
There are definite positives in some work rolling in too. Not only will the money be most welcome - but it will provide a distraction. It is much easier for our mind to wonder towards food if we are in the house.
Take care
