A woman had some problems, so she went to her doctor of twenty years. They had the following conversation:

Doctor: "Take the red pill after breakfast with one glass of water."

Woman: "Okay."

Doctor: "Take the blue pill after lunch with two glasses of water."

Woman: "Okay."

Doctor: "Take the yellow pill after dinner with three glasses of water."

After giving these instructions to the woman, she asks, "Can you tell me what's wrong with me, doctor?"

Doctor: "Yeah. You don't drink enough water."
