Thanks for your replies guys. I think for now I just need to avoid all social gatherings that involve the pub/club. Then from there I'll see if I can gradually re-introduce on a sober level.
1 thing I know is sobriety is the way forward for me. I've fallen into this habit of making some very poor decisions (drugs) when alcohol is involved.
I'll be keeping a good eye on this forum, particularly through any testing times I come across in my journey.
