Good luck! I've dealt with alcoholism in my family, and it sucks. Because of that, I have two siblings who almost don't drink at all.
I myself like a good glass of wine. And I've had some times when I used it to self-medicate with work stress and kid stress. So I totally understand. The other problem, with wine, food, and the like - is the people that you hang out with. If you hang out with drinkers, it's hard to not be a drinker.
Some maybe helpful tips: I have given up alcohol (for me, wine) for a month at a time in November a few times (along with wheat, sugar, and fried foods). I felt much better and lost weight each time (though it was probably mostly the wheat).
I have made "rules" like no drinking except on weekends.
I have found *other* things to do to relax - go for a walk, read a book, drink a cup of herbal tea.
These days, it's pretty easy. I still belong to 2 wine clubs, and I get 20 bottles of wine a year. I probably purchase maybe 4 more, for a total of 2 bottles of wine a month. Unfortunately/ fortunately - wine interferes with my sleep now. And I need my sleep. I have been working full time, I have 2 kids, husband travels, and I have been training for running races. Sleep is just necessary. So: I can't drink it after 5 pm or I won't sleep well.
Thus: I take my lovely bottles of wine to our weekly potluck. I drink 1-1.5 glasses. My neighbors drink the rest. Every 2-3 months, I may open a bottle at home and drink it over the space of a week (one glass per day). Many weeks I don't drink at all. In the end, it means my average alcohol intake is probably 2 glasses a week.
Which is fascinating - I visited the doctor this week. They wanted an estimate. I gave it to them. The nurse REALLY wanted to increase it "2 a day? 6-7 a week?" NO, 2 a week. (Because I've also read about breast cancer risk.)
On a side note, 5-6 bottles of wine a week is way too much. One per week is more along the lines of the max recommendations for health.
