What presidents, if any were drug addicts, alcoholics or mentally ill while in office

I met Ronald Reagan the same day that the Contra funding went up for vote. I asked him about a small point related to the Contras, and he had no idea what I was talking about. He looked up at Admiral Poindexter with the look of a deeply concerned but confused four-year-old.

He was in the process of walking to the helicopter for the first leg of a trip to his ranch to "rest."

When I heard about the Alzheimer's, I just thought "Oh, so that was it."
