I facilitate alcohol awareness groups for offenders who crimes are alcohol related, who have a problem with alcohol.
We advise that while aiming for abstinance is a good long term goal, the goal has to be specific, manageable, acheivable, realistic and timely.
Ie don't say to yourself that you will not touch that half bottle of rose in the fridge if you know that is going to be tough to do/impossible. Do not set yourself up to fail, feel worse that you did not acheive your goal and want a drink even more. If you normally drink 1 whole bottle or more say to yourself something like 'my goal is that tonight i will drink only that half bottle of wine, and enjoy it. Tomorrow, I will set another achievable goal'.
You may want to consider changing your routine slightly and add that to your goal so that you are not able to drink at 6pm. so maybe say, I will have two glasses of wine once I have finished the ironing/cooking/painting/talking to friend on phone, which will be at 8pm, and I will be in bed by 10pm. you don't have to change your routine by much to change the drinking routine.
If you think you will drink half to one bottle of wine, then say that to yourself. Make it real. Do not say 'only one glass' or 'none tonight' if that is not going to happen. If you have more than one bottle, say cut it down to half-one.
Do not put in place 'get out clauses' i will not drink unless I have had a bad time putting the kids to bed/had an argument with family member/tired/not drunk for two days/have friends round/want a treat etc. As you will always find one of those applies.
Going to cold turkey with alcohol is in fact quite dangerous.
