What do you drink on the course?

Water, Ginger Ale, and Mocha Double Shots.

[No Mulligans]

Sometimes shortly before the round, coffee black.

Always during the round, water.

Mojitos premixed in a thermos with plenty of ice. Yum.

on the course, two bottles of water in the summer, one on the shoulder seasons; a 5hr energy slug of sugar caffeine, and if I am not staying for a beer then container of chocolate milk on the way home.  I play courses with lots of forest areas.

[Pretzel]

Lots and lots of water. I carry an insulated 20 ounce bottle on the course with me and I usually will fill it up 7 or 8 times. Twice before I play while I warm up, then every three holes or so as I go around. It keeps me nice an hydrated and allows me to snack on jerky or granola bars without feeling thirsty afterwords.

[Yukari]

protein shakes and water.

Tried beer once and my game went south.  So no more beer on the course.
