Fascinating Question.

I have thought about it for a while. The immense boredom and loneliness would drive someone crazy. In that case I would never get the unlimited amount of drugs, because at some point you cross over to the stuff like heroin or coke. And with that it is over you probably don't even survive the 10 years.

I definitely would take the:
Kitchen(6) you are enclosed for a year. You have to eat right
Gym(5) need stress relief and good health

then either
Garden(2) especially if I can grow weed. Since I need to have some mind altering substance to pass the time. or grapes to make wine
5 million


Internet(16)- gives you communication, current events, entertainment
Garden(2) once again cheap source of mind altering substance
Pool table(1) once again last point
10 million
