Weight cutters I need your help

Can you guys tell me the basics in cutting water weight in a 24-48 hour period. I am trying to cut 10 pounds of water out of a 200+ pound weight over a couple days. Diet and workout will be in check up to that point, it is that I have never cut water weight before. I'd like to know how to:
1- Nutrition for the last 7 days
2- Water intake for the last 7 days
3- Water-food intake the last 24 hours
4- The use of sauna, sweat suits and bathtub
5- Over the counter or natural supplements to help with the cut

Crank up water intake to two gallons a day during that last week and minimize sodium. Cut out water 24hrs before weigh in. Your kidneys will keep cranking out water at a good rate-pulling off excess quickly. That will get you pretty darn close, then hop in the saunna if you are a little short. Rehydrate with Smart Water after you weigh in to keep electrolytes in check. Obviously watch your diet, esp intake of slowly digesting foods-take about 48 hours to digest some meat products. Hope that helps, and good luck.
