Hi, Cynthia:
Likewise.
Gatorade also upsets my stomach! Now I know that I'm not the only one who experiences ill-effects from drinking too much of this sports drink. (Another reason I no longer drink Gatorade is that, according to my dentist, the drink is terrible for the teeth. In fact, he said it's even worse than soda).
You can purhase coconut water at either Henry's Market (in La Quinta) or Clark's Nutrition and Natural Foods Market (in Rancho Mirage). I really like the Henry's in La Quinta; it's a lot bigger than the one I usually go to (their Rancho Cucamonga store), and the selection of organic food products is exceptional.
The ZICO brand of cocunut water comes in several varieties, including passion fruit, mango, pineapple, and, I think, strawberry. Henry's carries the Harvest Valley brand, which, as far as I know, comes in only two flavors: plain coconut water and acai. Clark's sells the "Amy and Brian" brand. It's good, but I prefer the other brands, since they come in tetra packs, not aluminum cans.
Intiallly, I was skeptical about trying coconut water, especially since I don't like raw coconut--but I'm glad I gave it a shot because, as noted, the stuff has boosted my hiking performance.
I hope to see you on the trail soon.
Rob
