Had a spell with heat exhaustion yesterday myself Nimrod , after catching our limit yesterday my buddy wasn't ready to leave so we just keep fishing catch and release until about 1:30 , had a spell hit me and thought I was going to pass out and puke had to put a cold wet towel on my head and neck for about 10 minutes then got to feeling a little better and called it a day, need to make sure and have plenty of water or gatorade from now on!
