That's insane. I know guys who bring a gallon jug of water to work, but I live in LA where we sweat like pigs if we work outside. It's that dry heat, you step out the door and are immediately sweating. If I tried to drink that much sweet tea I think it would overload my body with sugar. I had a banana-date smoothie once that made me shake it was so loaded with sugar...I don't even try to do sweet drinks like that anymore.
