I had a look in your 'Snufkin thread' to see what has been going on.
Snuf - you are early recovery - very early again now. You must not go to pubs, especially with Mark. You two, you said, are beyond broken and the fact you are still living together seems triggering, especially as you argue so much. That's just not a healthy way to live. I know you are looking to move to Glasgow.
Drink lots of water today.
It is possible to get sober but I think the further down you go, the harder it is on the journey back up. Please love yourself enough to help yourself. You have so many supporters and friends at SR.
