Extremities "fall asleep" because the flow of blood is interrupted to the nerves that control them. The nerves actually "go to sleep." Usually happens when clothing or some object pinches the artery going to the arm or leg. So, check for things that can do this and maybe it will help you keep everything awake.
I think you can try sitting on something soft other than sitting on a bare floor. You can also sit with your legs apart so as to allow blood circulation since when you cross your legs, the circulation will be cut and pressure will be added.

Your blood circulates all around and through you're body. When you cross your legs sometimes, you could be blocking/crushing the circulation path. Always move often or change positions when sitting or crossing legs. You're legs probably fall asleep because they haven't had enough circulation in that area. They fall asleep because they also haven't moved in a while. Just like when you're running, your heart beats faster, because while your running and your moving more, your blood has to circulate more, therefore you're heart beat speeds up.
