How is your potassium intake?
No, seriously, if your potassium is low, you will still retain. Also any food allergy can cause water retention. I have this problem too, and am by now convinced that I do not tolerate gluten. I am doing much better on gluten free diet, no diuretics any more. Still have some fluctuations every now and then, but nothing compared to what it used to be.
