Thanks everyone! I've read every reply, and there are some very good ideas there.
I drink 2 bottles most nights. I'm used to it, of course. I was doing really well earlier in the year, and was having 3-4 days alcohol free nights every week. I've somehow slipped back though. I had one night off last week, and probably got 30 minutes sleep! All night staring at the ceiling!!
I think I need to get some sleeping tablets. I've got herbal gummies, but they don't help at all. I also got lavender spray for my pillow - no help either.
To those asking how it came to this (!), I only used to drink a little until I was about 35. Then I found out that my long term DH had been cheating on me, for our whole 20 year relationship. I left him, but we had to live in the same house when this was happening, and I found myself drinking more and more wine to cope. I seem to have had a problem with it since then. But I am now in my 50's! I am from a family of alcoholics, was raised around a tonne of booze, but that didn't seem to affect me until my marriage fell apart.
I am now very happy in life, lovely DH, kids grown and doing well, lovely holidays, plenty of money (hence cost not an issue). I am not a rowdy drunk. I just open a bottle at 7pm with dinner, and drink slowly until I go to bed around 11pm. That's 6 large glasses of white wine, which is 2 bottles. Never feels a lot when I'm drinking it, as I'm not chugging it. DH also drinks, but he has a good few nights off because he works shifts, so can't drink on those nights.
We have loads of spirits in the house, gin, vodka, brandy, whisky, you name it, but I never touch those, even if we were out of wine, I wouldn't go near them. They are bottles we've been bought as gifts, and DH buys them if he likes the bottles. Goodness knows why, because he never drinks them either.
I don't smoke, and I've never done weed or any drugs of any kind. Not that that's relevant, I guess.
