Things like chewing gums, biscuits and peanuts always does the trick.
It is very nice you are not taking coffee to keep you awake but then it's also bad to send any solid aside water down the GIT at that hour of the day (midnight) because of reduced system activities.

Unlike you, I was and am a night owl so I need very little of these methods to stay awake since it's just in me.... I prefer sleeping by 4/5am and waking up around 9/10, those are when I enjoy my sleep 😂
