Yes, we are a bag of chemicals in water.
When I go to gigs, as well as peanuts, protein bars, fruit and hopefully some decent chocolate, I take lots of beverages!. For quite awhile I took Gatorade. For a three hour gig maybe 3 of the 20 oz bottles. One or two would be frozen solid from the freezer. Often they stay cold 'til the end of the gig.
This last while I've been using Propel instead - I like it better.
Here's the thing - for some reason you can drink way more of a sports drink (sugar) than straight water. If I have a glass of water, I'm lucky to drink 1/2 of it on break. After 1/2 I feel bloated and it's almost nauseating to drink more. But with a sports drink I can pound it and drink the whole thing no problem. Plus you get electrolytes. Sometimes you can feel pretty spaced when you sweat a lot. Unfortunately sports drinks do rot your teeth.
There was writing on Gatorade bottles once that said that they took 2 football teams and at 1/2 time one replenished with Gatorade and the other water, and that the Gatorade group outperformed the water group. That's been my experience too. It's like using Miracle Grow instead of straight water on a plant.
