Dont reduce on your subutex script. Have a really honest conversation with your prescriber about your relapse and your fears even if this means being placed on daily collection. It might have saved me a few relapses
Do not continue on drinking like its Christmas in January, telling yourself 'its fine' because its actually unhealthy and will be difficult to stop
Replace your work equipment now, dont put it off because you think you never wfh. I requested the damn thing in March and it's still not materialised
Work on your self esteem, you're better than you think
Put in boundaries with a relapsed NA friend. Do not spend 50quid on food shopping for him, or buy him cigarettes, as this will lead him to think you are a cash cow
Go on meetup meetups. Youll enjoy it.
See your parents more. Yea they're hard work and mam is abusive but you will miss them when you cant see them at all.
Start making the effort to cook. Itll probably take less time to do than waiting for a takeaway and is healthier.
