I just can't stand having no contact with him.
Then you are setting yourself up for a world of misery.
He likes to go out & get falling-down hammered now & then. From your post you seem ok with that. However as you're clearly not ok with losing contact with him, & spend the time "worrying" about him, maybe that's the issue you need to work on.
Have you ever attended a course along the lines of assertiveness or similar self-empowerment? Because it's sad that while your bloke gets to go out & do what he wants, you are wasting your own time with needless worry & yearning for contact. Can you not focus on your own hobby/evening out with friends/luxurious 'night off' evening in with yourself ...?
You are making yourself miserable over ONE night of no social media contact with him. This is why I feel you would benefit from some kind of self-help training, because until you build the internal resources to be able to rely on yourself for occasional periods, you are going to continue feeling fretful & anxious when your boyfriend is out without you.
Your available options are either to change boyfriend, to one who isn't interested in all-night benders, or to work on making some internal changes to yourself. Making the changes to yourself would give you a lifelong skill at being able to look after your own emotional state when you are alone - a huge benefit that will stand you in good stead throughout the future.
Why is it that you worry about him?
What is it specifically that you dislike about not being in electronic contact with him for a single night?
If you are able to work on questions like these, with an experienced counsellor/therapist, you will be giving yourself a huge gift. You can't control your boyfriend (& if the relationship is right for you, you shouldn't feel that you wish to) - but you CAN control your own response to the odd night without his company.
I hope you find a good expert to talk to & resolve some of these issues, because being unable to be alone for an evening without worry, anxiety, & a need to be in electronic contact is no way to live, & I suspect indicates some deeper seated issues: a professional counsellor could offer you a good deal of help & comfort in managing those.
