There was something on the news last night about an breakthrough in drugs to treat auto-immune conditions, @WendyWagon. They were talking about Lupus, but said that it was very promising for things like MS and RA too.
Honestly, moving house - particularly selling a house - is stressful enough without adding hangovers and relationship problems to the mix. Get all your wagons in a circle, and ducks in a row and soldier on.
I second @Lavrander about the 4-8 week period being hard, @Kakkilakki. Your sober muscles are still untried, and yes, the novelty has worn off a bit. Give it to about 90 days - at that point your new habit will be not drinking, you'll have developed new and more personal ways to do that, and it will all seem easier.
I found that early nights (even when I knew I wouldn't sleep) helped. I'd have a hot bath and a box set to get me through if insomnia struck. I bought fancy scented oils, which I used in the bath and in the bedroom, which I kept clean and tidy, and bought sleep headphones and a million tracks of hypnosis to listen to. I stuck firmly to a routine - run the bath and switch on the oil diffuser in the bedroom, have a scented bath and get into a warm bed (electric blanket in winter) and relax. If I was definitely not sleepy, I'd switch on the TV - Downton Abbey and Stella at first, then others I've forgotten. I went for easy to follow series that I could watch without paying attention, but would stop me getting bored and thinking too much. When I was ready to sleep I'd put on the headphones and listen to the track du jour (or du nuit) and hope to fall asleep. If I didn't, no stress - I just watched another episode. Taking the stress away really helped. It took ages to get a decent sleep pattern going, but in the end it wasn't too bad. It worked for me, but you might prefer other strategies.
Some like quit lit, but I found it tortuous - like reading books of baking recipes when on a diet. Some go to meetings, but I didn't try them. I posted online instead, and that helped, too. I didn't drink for over eight years, and thought I was over it, until something happened that made me (stupidly) start again, and I'm wobbling now. I'm not 'a drinker' now though. I can just as easily say no, and I'm determined to get back to that being a rule. You will work out what suits you in time, but throw everything at it at first.
Oh, and take plenty of Thiamine (vit B1). It will help to prevent brain damage from alcohol, which can develop when people stop after drinking heavily for a while. Good luck.
