Hi Mel. Welcome.
You've come to the right place. It's difficult to change your life when you're in the habit of drinking every night. SR is a nice supportive place to discuss your thoughts and challenges as you go through this.
It helped me a lot to revise my thinking. Instead of thinking of alcohol as a treat that I owed myself for a hard day's work---I reprogrammed myself. I made myself think of it as a poison, and I was so much better off without it.
Like many other people I was worried about my health. The fear that I was permanently damaging my liver or brain was a good motivator.
It may be difficult initially in social situations (depending on where you live) but there are good threads on that you can reference. Really it isn't anyone else's business!
Anyway...glad you are here. I haven't had a drink in almost 3 years, so I know it is possible. You can do it!
