Bad idea. I have learned through much experience that two hours of sleep is better than none.
If you have the option, just take a "nap" on the couch instead of falling asleep on your bed. It's much easier to wake up and get going if you just fall asleep for a little bit on a couch. Rather than a comfy bed.
And maybe get a 5 hour energy drink before you go to wherever you need to go.
