Unsure what to do with myself

Had my worst set of withdrawals over the last three days (as would be expected from kindling and my intake).

I have a coursework due in a week with probably an average 9 hours of work a day, and an exam period two weeks afterwards, probably following the same intensity. I don't want to give up on uni, but I'm registered with a clinic which can provide me a free detox / rehabiliation following this period assuming I make it there.

Does anybody have any coping mechanisms, or motivation-based mechanisms that could apply to someone like me? I think I can drink enough at a suitable time before bed due to the ramifications of relapsing again, but my brain feels like mush and I don't know how I'll be able to motivate myself :/
