On rides from home, I use the bottled Gatorade rather than the powder, even though it is more expensive, simply to get a larger variety of flavors. I stock up when the 32-ounce bottles are on sale for 59 cents.

On tour, I don't want to carry the weight of the powder, and I'm not willing to pay $2.50 for the bottles at many convenience stores, so I just drink water. Furthermore, because it's often harder to thoroughly clean your bottles on tour, I also prefer not to put mold-growing stuff in my bottles. Finally, on most tours I usually pass through towns frequently enough to get food and drink, while my rides from home usually seek out unpopulated areas where I must carry my own replenishments.

Sorry to provide more information than necessary to simply answer the question, but this would be a very dull thread if everybody just answered with only "yes" or "no".
