Hello, glad to see you have come back and reaching out for support.
I had many many failed attempts at sobriety so you are certainly not alone in that respect.
For me personally, I had to force myself to reach out to family, friends, professionals and admit openly that I had a massive problem and needed help. Spent 3 weeks in rehab and now sitting on 103 days clean.
If I can do it, anyone can. Before November last year I couldn't go more than 1 day without drinking to oblivion.... and that 1 day was only because I was soooo ill and hungover.
Anyhoo, I hope you find the strength to stop for good. Lots of tips, support etc here
