Thanks for sharing milly3. That's useful information. I've embarked on a similar experiment a few days ago, and haven't gained any water weight. I'm feeling better for it and positive I will see good results. It's making breakfasts a lot easier to prepare and hopefully will save me a bit of cash to spend on other things.
