How to stay awake for important event ??

Someone I know has a baby shower at 2 pm . It’s currently 3:13 am and I’ve been swept away tidying my room. I still need to have a shower, that will take a hour since I take for ever .

I really want to go , and not sure if I should try sleep. If I go to sleep , I won’t wake up however and I don’t want to miss the event .

If I do stay up, any tips on staying awake And not feeling horrendously tired would be appreciated.
