I did this once, to try to control my oversleeping (10+ hours a day). I put my mattress into a closet and slept on the floor for a year. Eventually I just got used to the floor. It became pretty comfortable. I even returned to sleeping on my side after a few months. I've since found a found some far better ways to control my sleeping habits: - Eat more. - Get a job where you must wake up at 5:30, combined with a lifetime habit of not going to bed before 11. - Sleep under windows facing the sunrise, and don't close the blinds all the way. I can't going to generalize these for everyone, but I can say it worked for me. Sleeping uncomfortably just didn't work over the long term.
