I carry a cooler with ice and bottled water or gatorade to rehydrate. I've worked some long hot days and nights and forget to drink because of being so busy and not wanting to take the time. We've been having some pretty hot days now and I felt lightheaded and dizzy the other day so I make sure that cooler is in the truck with me and I keep bags of ice at my parents too where I work from a lot so I'm sure I have stuff on hand now. Thanks for the reminder OP, its easy to forget.
