I also use the Emergen-C packets in my backpacking and bug-out bags. I’ve had the most success with them in the higher humidity here in the SE. The tubes with electrolyte tablets (NUUN) are pretty decent as well. The big challenge is to have a dedicated water bottle as the sugars can quickly feed bacteria. I typically drink the electrolyte mix and rinse the bottle out with fresh water (drinking the ‘flush’) so I can clean it as best as possible. Care does need to be taken if really dehydrated as water needs to be consumed before the electrolyte mixes for better absorption.
Those “go beans” are like crack for my wife and I when on the trail. They didn’t sit long enough to turn into a gooey mess. After the first few days on the trail, we didn’t make coffee in the morning or eat breakfast. Instead, we packed up and hit the trail in the pre-dawn darkness and after a couple hours, we would snack, drink water and pop some of those caffeinated “crack beans” which were simply awesome. Maybe it was the caffeine or just acting as a placebo, but when the terrain turned rough or we were pushing through the last few miles, they just seemed to give a little “kick”.
Another aspect is to not wait until you visibly see signs of heat exhaustion or dehydration. Once you start getting cramps, it takes a lot longer to address and recover from symptoms. This is another reason why snacking and eating helps maintain much of that electrolyte balance along with copious amounts of water.
