You've already taken it, even accepting/realising there is a problem is a huge first step. If you search on MN there is a whole topic area, I think it's called alcohol support or something but hopefully someone might be along to post the correct link/title soon.
If you Google your area and community alcohol support services you will find free confidential support. They will be able to assess your needs and arrange either 1 to 1 or group help. There is AA. Personally it wasn't for me, but I know lots of people who it really helped. There is a thread in Relationships Brave Babe's Battle bus. You will get lots of support and advice there. I'm an alcoholic in recovery. Contacting my local community service honestly saved my life. I nearly died twice and would never have believed I could live without alcohol. So know that you can change this with the right tools and support. You've made the hardest step by seeing you have a problem and asking for advice
Hope you're doing well this morning OP! Just wanted to mention on AA - you really don't have to be religious to go so I wouldn't worry too much about that to start with. Just go and see if it's for you
I second the above poster re AA. It's not religious. They do talk about a 'God' but that 'God' can be anything you want it to be. Plus they are an incredibly friendly bunch of people all in the same boat and the support/friendship and advice can be truly amazing (and incredibly helpful).
