As a wrestler through high school and in college breifly, I would highly reccomend drinking at LEAST a gallon or water per day. And by water I DONT mean vitamin water, I DONT mean soda, I DONT mean Kool-Aid. Take a gallon jug and fill it with straight water. Lighten up on your diet, 2 or 3 small meals of fruits veggies and maybe a 2 oz chicken breast would be a great start. the water will help hold back your hunger, if you take protien/creatine that will help muscle performance/recovery and also slightly stave off your hunger.
And most importantly... DONT CHEAT! One big meal or fast food inbetween can KILL your progress. Trust me... Ive messed it up before. And you would hate to cut 8-10 lbs in 24 hours. :/
