After consuming large amounts of alcohol and laying horizontally on the back or stomach, usually on a bed or couch the world will start to spin around you. If left unchecked this condition could enduce premature vomiting.
Easy remidies are as follows:
1)Put one foot on floor
2)Roll over onto side
3)Put two feet on the floor, get up, walk to the fridge or make your way back to the party and start drinking till you pass out. Don't stop now, your almost there.
Dude, Jimmy got the bed spins so bad last night he puked all over his moms $3600 leather sofa.
