A medically supervised detox is something I have definitely considered. I've just heard stories of people that have been drinking heavily for 30 plus years that have managed to get sober without it, that I thought maybe as I've only been drinking heavily for around 7 years and I'm still young I could do it on my own without medical bills etc. It's not a pride thing, I've swallowed that a long time ago.
I've accepted that I'm powerless to alcohol. I'm hoping that if I admit everything to my girlfriend she will help me through it and be there if things start to go wrong.
