Do multiple stretches, spread your legs when standking and touch the floor, then try and get both hands on your right foot, then both on your left foot, hold each stretch for a bit. After that you can do lunges where you bend your right knee to the right and keep your left leg straight, strethces out your left leg, repeat on the other side. Put both feet together and try and touch the ground. Cross your legs and try and touch the ground. When you sit down do pretty much the same, pull one leg closer to your body and then try and reach both hands out to your outstretched leg. Stuff like that. The more different stretches you do the more flexible you will become.
You're not drunk if you can lie on the floor without holding on
