Kandaf and AquaDame - great ideas! I'm going to go look into both. I have always shied away from anything other than water because I thought I had a sensitive stomach, but perhaps it's the other way around... I have been using a Gatorade recovery drink (the chocolate milk protein one) after my run. Could that be causing my issues? I thought that would help. Has anyone used the Accelerade stuff that Jeff Galloway recommends?
