Thanks all for your replies. I'll just hang in there and keep an eye on things. Have changed nothing in my eating habits, and 3 litres of water is probably the minimum I would drink. I am taking in more the last few days.

I do not buy salted nuts.. only the raw variety. I stuck to a protein drink and 1 pancake (made with WPI, egg and flaxseed meal) for breakfast, a tin of tuna in olive oil and salad, 1/4 avocado, and 40g of raw macadamia nuts for lunch.. dinner is almost always cabbage or other vege and lean meat. A nice dollop of cream and sugar free jello for desert.

Still swollen today, but not quite so grumpy This too will pass, literally.
