OMG - water weight is awful, good news is it's practically predictable with certain foods and alcohol. SO be prepared and don't let yourself freak out, just add lots more water and add in some food that are notorious diuretics!
The following foods and herbs are know to have diuretic properties:
■Melon / Watermelon
■Aim to eat small amounts of starchy carbohydrates (such as breads, rice, etc)
■Avoid salt and salty food products.
■Drink plenty of water and herbal teas.
■See herbs above.
■Avoid sugary foods.
■Eat fruit and vegetables.
Low fat natural yogurt with fresh fruit
Slice of whole grain bread
Serving of baked chicken (with garlic and lemon juice)
Steamed broccoli and carrot

This stuff helps me!! Basically WHOLE Foods, no processed junk. Good Luck!
