Follow up: Have decided San Pelligrino isn't a regular option due to the bubbles; however, it did seem to quickly resolve leg/foot cramps and very dry lips.
I've started with SaltStick caps instead and that seems to do the trick, as well. Hard to say, but seems I do not need to drink quite as much water to stay hydrated. It's nice that it's very portable, as well.
Aside from taking during exercise, I'm really not sure how many/frequently to take the SaltStick caps for our pouch purposes. I'm taking 1-3/day, depending on how hot it is and activity level. Does anyone have recommendations on this?
