Dear
@Kittyruns , I'm glad you raised this question - I hope my perspective can help. I quit alcohol about 3 years and, um (counts on fingers), five months ago and it's one of the very best, most self-caring and life-enhancing things I've ever done for myself!

And I definitely think it helped/continues to help on my TMS journey.
I had the 'hangziety' you describe for decades - and every time, a drink seemed to be the 'cure' for it - and of course, that just perpetuated the cycle.
I'd tried and tried to quit, and then I got breast cancer (which can have a link to alcohol, of course) and decided 'what the hell - I can turn this horrible year into a positive one by doing this good thing for myself!' So I quit the booze (and then vapes a month later) (and eventually codeine), and of course the early days were hard beyond belief - my usual coping mechanism gone... BUT - in a few weeks I was experiencing levels of calm that amazed me. I was sleeping better, my energy was more level. Basically, it cleared a lot of the crapola out of the way and I got to 'sit with myself', knowing that my emotions were real, and were bearable, and not a withdrawal-induced over-reaction that I had to escape from. Stuff got a lot
clearer.
I'm not rabidly anti-booze - I just know quitting was the best thing for
me. Drinking certainly felt allied to TMS in that it was something I could obsess and pick and worry over... it was a handy distraction from the real issues that I was afraid to face.
Do I even have to mention the clearer, brighter skin? My body getting sleeker, lighter and less puffy, even as I chocolate-binged the first few weeks (okay,months)?! Sober people do tend to bang on about it, but that's because it feels so good and we want to share that. Some people are well and happy with their glass of wine, a few beers at the weekend - a little treat that doesn't rule them. I couldn't do that. I was either drinking and regretting it, or not drinking and feeling deprived. It has simplified life so much for me, and I'd advise you to give it a try!
I read Jason Vale's book on quitting, and followed a British blogger called Sober Mummy/Clare Pooley (mummywasasecretdrinker.blogspot.com), as well as dipping into other sober lit. At first it did obsess me a bit, and I thought I would count every day forever, but now I have to really think about how long it's been, and it's just how I am, I just drink things that aren't alcohol, mostly cold, sparkling water. My journalling now gets to the nitty gritty or the gratitude, as required, rather than being pages of self-recrimination for drinking too much
again...
Anyway, this has turned into an essay, as I knew it would, but I hope it helps! Give it a month to start with, perhaps? I wish you well!
