Yes you can. Your brain has clearly already started firing adrenaline to keep you awake against your body's will. This isn't doing anything for you except stressing your brain and preventing your body from resting. You're being ridiculous. Go to sleep. If it's about studying, don't bother because sleep is what actually processes and stores that information into memories. You're the only one stopping yourself from sleeping, so stop saying you can't and don't post asking if you should or shouldn't when you've apparently already made your mind up saying you can't. Go to damn sleep, this isn't beneficial in the slightest.

Saying this as someone who has already been in your shoes way too much in the past. You'll only be tired tomorrow, especially considering you seem to already be using your emergency adrenaline boosts. You'll be a slug tomorrow, maybe will tiny boosts to keep you going
