I did that, I was drinking a bottle a night for 6 nights with 1 night off.
I ballooned, I have since cut down but it's down to working 3 evenings a week and needing to stop. Money was beginning to get very tight as well and at £6-7 a bottle everynight it was just geting too much.
Plus I was getting a ain in my kidneys, unrealated, maybe, maybe not but It made me scare enough to stop.
There is no magic way you are just going to have to stop and just only drink at weekends. Friday and saturday night only and make it a treat. If needs must only one day in the week.
But in all honesty if needs must then theres a problem.
I don't know about your circumstnaces but could you not take yourself off out for a walk in the evenings when you fancy a drink? or clean or declutter a room. Do something to take your mind off it.
this might help.
£1872. that's what you'd save if you didnt drink. (a year)
or £936 if you had 3 bottles a week. (a year).
do you think you have a problem or is it under control?
