Murienn, the Bolthouse Farms drink would be more than I need. I basically just want electrolytes. I get everything else from real food or Shotblocks when I need a lift. I used to use Accelerade, but it's too sweet for me and hurts my stomach, too.
I might try the Heed if I can find a packet in a LBS. yesterday, the Gu20 was fine, but again, too many calories.
