I cant fully remember, I did it for a month, but stopped over Christmas - starting again now.
I think the first few days were hard, but you get used to it.
The improvements were pretty massive: my lower back was less curved than previously, I remember dreaming more, and overall felt better. Some of it may or may not have been placebo, but the most important things when it comes to sleep have to be implemented together. You cannot simply decide to sleep on the floor and think that that will cure all your problems. You have to start incorporating good habits together, e.g. sleeping on the floor, not looking at a screen before bed (blue light so LEDs count too), eat 2 hours before sleeping, and so on.
I should write an article on this one. Very interesting topic
