Hey can you guys help me?

I got band camp next month, and well be outside in 90+ weather. And i dont particularly like water, and i dont wanna end up dehydrating. And i dont want my kidneys to fail from drinking juice all the time. We have gatorade and a water cooler and all but im not a big water drinker. Also me bein african american, by the time band camp is over, i will be as dark as my clarinet. How do i not get that dark, besides sun screen. Also i have a wooden clarinet, and well be out in the heat, it survived last year but im kinda scared of the wood cracking and i dont have the money to get a plastic one. What do i do to prolong the life of my clarinet?
