A man goes to his doctor because he’s been feeling very ill for days. The doctor gives him several sets of pills.

The doctor instructs; “Take the green pill with two big glasses of water when you get up. An hour later, take the white pill with another glass of water. Take the blue pill with a big glass of water after lunch. Mid afternoon, take the orange pill with plenty of water, and repeat that at dinner. Then, just before going to bed, take the red pill with several big glasses of water.”

The man is alarmed at huge volume of medicine he has been given to take, and nervously asks, “What’s the diagnosis? What’s wrong with me?”

The doctor says, “You’re dehydrated.”
