Living a lonely life away from the planet is not an easy task as it may look like.
Sometimes astronauts cannot bear this loneliness and get hyperactive. NASA also knows this and they have a procedure to deal with such emergencies.
The procedure includes restraining astronauts with duct tape and injecting them with anti-psychotic drugs like Haldol or even tranquilizers if the scenario is even worse.
The checklist also says that if a astronaut does not cooperate then these drugs can be forcibly given with a shot to the arm, and then the crewmates have to monitor the vital signs of such astronauts.
Astronauts aboard the ISS get to talk to a flight surgeon once a week and once in two weeks to a psychologist. During the remaining time they are on their own and seldom say words that can make other astronauts shoot a tranquilizer dart at them.
