Right, bit more background. My drinking was also prolonged (20 years) and had always been heavier than people around me but not insanely so until the last few years. I had a problem way before I was drinking in the morning.
I was incredibly ill. I have literally no idea how I dragged myself into work every day. It was so hard to walk to the bus stop. I was throwing up every day (bizarrely and unhelpfully the only thing I could keep down was booze! Bloody body). I made an appointment to see my GP, I can't remember what for. I don't think I intended to come clean about the drinking. I was talking to one of the mums in the playground and (as had been the case for some weeks) I was too weak to stand up whilst we waited for the bell to ring. She decided enough was enough and phoned my practice to say I had to be seen that day. I think I had had to call in sick as I was at home when my GP called me back later that morning saying I had to come in. I was like WTF - this never happens. Anyway, I went and he told me later he thought I was dying - I had lost so much weight.
So that was the turning point. I've been sober for over three years. Of course there are differences in our stories - I was drinking every day, you're almost certainly not as ill as I was. But the fundamental elements of the story are the same. I knew I had to quit drinking. I wanted to cut down but I couldn't. As I started to deteriorate, using addicts' logic, I wanted to drink more because I knew I would have to stop soon.
Going to see my GP set me free. Finally I had admitted it and I told him the absolute truth. I realised then why truth is a necessity to recovering addicts - addiction thrives on secrecy. It was easier to tell people when I was so unwell, just to get it done and over with. Now everyone knows - friends, family. Mumsnet has heard all this stuff many times as well!
I used to read threads on here about addicts who had quit and how much better they felt and think 'well I couldn't do what they did'. I thought that right up til the day I did it too. Obviously recovery is a process, not a state - I will always be in recovery and three years is actually quite a short time (doesn't feel like it when people are bitching about doing the January Dryathlon on Facebook and complaining about how hard it is 
).
The book that really helped me was this one. Totally non-judgemental, it eschews the term alcoholic in favour of problem drinker. You are certainly a problem drinker.
There's no better time to start than right now. Your liver is in a better state now than it ever will be again, if you don't take action. Get yourself to the GP - you will never, ever regret it. Good luck.
