Agree 100% stay away from the Minute Maid frozen lemonade I made the mistake of eating 4 because it was so hot just made me thirstier and sick to my stomach way too much sugar. The wife kept saying drink water as usual she was rightSomeone mentioned Gatorade because of the loss of electrolytes from sweating. I urge you to be very careful with sweet drinks, candy, soda pop etc. 9 times out of ten when people get sick to their stomach on the bus it's from consuming surgery snacks in the Florida heat. Also coffee will dehydrate you.
