Hmm...
Alternatively, Camelbak now sells sugarless tablets for flavor & electrolytes that they say won't make a mess. They use sucralose for a sweetener, and come in lemon-lime and orange flavors (plus the orange has caffeine
). One tablet is good for 24 oz., so you could use one in a regular bike bottle, too.
I haven't tried them, though.
