OP, I completely get you, I was very similar until recently, I could easily put away a bottle a night, it helped to relax me, I loved the taste, it didn't even seem to make me very drunk, it made me happier and helped me cope with stress.
However, unfortunately I had to see someone close go through liver failure and I wouldn't wish that on my worst enemy. I really went off of alcohol, not really through will power or anything, just it really didn't seem very appetising all of a sudden. I didn't make a conscious decision to stop, I just kind of stopped drinking, which is something I never thought I'd do.
What's been interesting is that it completely was just a habit! I've found that now I'm doing other things in the evenings, I don't even miss it. The other day I had had a really shit day, and thought I 'deserved' my old friend the plonk. I bought a half bottle of prosecco (previously I would have laughed at a half bottle), as the whole bottles now seemed huge. And weirdly, I didn't even like the taste! I didn't even finish the half-bottle, I had some left in a glass the next morning and I poured the rest away.
This isn't meant to sound preachy in the slightest, it's just been astounding to me how all the things I used to roll my eyes at hearing have turned out to be true. My bottle a night wine habit was just a habit, I don't even really like the taste, and I don't even miss it.
I'm sleeping better, got more money, more energy, someone today asked if I'd lost weight and I've literally not changed my eating at all. All the cliches, both the positive and the negative ones, do seem to be true.
I'd have done the biggest eye roll though if I'd heard all this 3 months ago though.
