Last summer I got myself in a very dangerous on course situation. It was a 95 degree day with 90 percent humidity. I didn't drink any water before playing and I was walking. By the 7th hole I literally almost passed out. Blurred vision, stiff neck, bad. A playing partner gave me a vitamin C packet which I mixed with some water and I gradually felt better. The rest of the season I added a pedialyte type product to water and it seemed to help. somewhat. Does anyone have any suggestions on a product I could add to water or any drink , to keep me hydrated and prevent me from dropping dead playing the game I love? LOL
