Well, it depends on what's in the room. The urine drainage bag at the foot of the bed. The bottle of hydrogen peroxide on the bedside stand. Perhaps he can talk a family member into filling that container on the shelf over the sink with water. Little does either of them know that we use it to measure his urine output and liquid stool.
Alcoholics are even more fun.
They tend to be exceptionally thirsty patients and exhibit a lot of poor judgment and originality in what they will drink. That may not be such a symptom as a cause of alcoholism. They'll drink right out of the toilet, they'll drink hand lotion, they'll suck alcohol swabs in an attempt to feed their jones. Hey, speaking of alcoholics and poor judgment, don't mix your antifreeze with alcohol if you really want to off yourself. Orange juice would be better.
