How to lose 5 or 4pounds in 10 days ?

I'm going to Florida in 10 days. And I need to lose weight fast! I wanna weigh 135 but 136 is fine too. I work with my dad doing Drywall so it's hard to eat healthy at lunch. But I have a program and it helps track my calorie intake and exercise. So I never eat more than I'm supposed to. Someone please help! I have to lose this weight!
