Patients can be treated with oral rehydration solution, a prepackaged mixture of sugar and salts to be mixed with water and drunk in large amounts. This solution is used throughout the world to treat diarrhea. Severe cases also require intravenous fluid replacement. With prompt rehydration, fewer than 1% of cholera patients die.
Clear Karo syrup in water is good too...
Repeat frequently, drink what you can hold.
It got me through 5 days of a nasty bug like this. Gatorade or sports drinks are good if you have them.

Yep, aka Pedialyte. Once rehydration is taking and the patient is ready for solid foods, switch to the BART diet (pick one and go):
b - banana
a - applesauce
r - rice (plain)
t - toast (plain)
to stop mild diarrhea.
