Try issuing it a second or third time and you will be parallel to the ground.
I am not sure what repercussions may come from using this, so be sure to make backups,
After issuing command click respawn.
After around 2 /sideways you need to do /suicide or something similar otherwise its stops working.
I ASSUME NO LIABILITIES from the use of this plugin
