Hey Hana,
I also have issues with alcohol and I used to be a massive wine fiend like you. Particularly when I lived by myself and I could get away with it. I've managed to limit the house drinking to just the weekend now, but even that has to stop.
Anyway, if you're like me, the two small bottles just won't cut it, cos once you start, you want the whole lot. Could you replace the wine with a sweet treat that you enjoy but that has less calories (for example, standard bar of chocolate) for a bit just so you still have something to look forward to but it's not as detrimental to your regime? I know the chocolate doesn't last as long as a bottle of wine can!
I just made a rule for myself that I can't drink during the week (from Sunday to Thursday) at home. I just felt I wanted to be fresh in work more than I wanted that fix in the evening. I'm not working at all now, so I could very easily slide back into it and it wouldn't have the same impact, but I haven't, because I've just realised it isn't worth it.
The weekends are another story, but I'm trying to tackle them as best I can.
Anyway, all these habits take time to break, it really is just a habit, don't get down about it, you'll get there.
