how do i lose 3 pounds real fast, wrestling Options

[OkamaPower]

i have a wrestling tournament tommorow. and i gained 3 pounds. i weigh 115 and i have to cut down to 112 by tommorow noon. sweating it out i guess wont work for me because its hard for me to sweat alot. i cant really run because i ran more than 9 miles yesterday making me sore today and 2 miles today and my ankles and knees are hurting. i think i can run when i wake up really early but i have school. first science , english and pe. PE wont really help because im swimming in pe. i cant swim and i have to learn by two weeks or i fail. im starting to learn on my back though but still, i cant skip out. all i need is to lose 3 pounds.
im going to:
stop eating until i weigh in
exercise early in the morning
sleep with 3 blankets to sweat myself
