I packed up drinking alcohol last year after I added up that I'd got through more than 90 pints in under three weeks. I'd mostly drink at home so I'd drink myself stupid as I didn't have to worry about finding my way home after.
What worked for me, was finding something to replace it with. I started drinking mineral water instead and I was getting through four litres of it per day at one point. I just needed to be drinking something.
Now, I couldn't care less about getting drunk. There are times and occasions when I want to have a drink and occasionally I do, but for the most part I don't bother with it any more. Life's been a bit stressful of late and I've had a couple of "I could do with a pint or six" moments, but so far I've kept it all under control.
Congrats on packing up smoking anyway. You'll live longer and people won't be able to smell you coming a mile off.
