Hi twoteens and welcome - well done for plucking up the courage to post, and well done for deciding to do something about your drinking. Even acknowledging to yourself that it is a problem is a big step (and one that feels very scary), actually posting it on a thread, takes the next step. So you've made 2 big steps already.
It isn't surprising that you feel rubbish. If you've been drinking pretty much every day, then your body has not really had much of a chance to really ever completely get rid of the effects of alcohol - this is probably the first time you've been really booze free for a long time. We sometimes talk about on here as 'seeing the hangover through to the end'. I know that when I was drinking it wasn't something I ever did. I may not have been swigging vodka at 10 in the morning, and infact most mornings I woke feeling crap (not always hungover, just lethargic and dull and rubbish) and promising that I wouldn't drink that day. Until the worst of my feelings wore off a few hours later, and the next bottle of wine seemed like an attractive option.
If you've suddenly stopped drinking there's going to be a lot going on in your body - a lot of detoxing and you will be missing the sugars that you had been accustomed to. So, my advice, fwiw, is to treat yourself nicely and gently, drink plently of fluids, whatever you enjoy - tea, hot chocolate, lime and soda, herbal tea, orange juice, banana smoothies, have some chocolate if it satisfies the craving for sugar. And take vitamin b supplements because alcohol depletes vitamin b in your body.
If you feel that you have cravings for alcohol, then the best thing is to make sure it is not available. So if you have lots of bottles in your house then get rid of them, or lock them away, or give them to a friend - it can be pretty hard to resist if you have a bottle of wine sitting there. And then change your shopping habit so that you're not tempted to buy any - avoid going to a supermarket if you can, shop in a butchers shop or greengrocer or halal store, anywhere that doesn't sell aclohol. Or shop online, and put your order in early in the morning when your resolve is strongest. Try to find things that will fully occupy your mind and your hands and your mouth. Knitting is good, chewing toffee is good. If it feels too awful, then have a hot bath, put your pjs on, clean your teeth and get into bed.
The really good news is that it does get better. You will stop feeling crap. It is possible to get througha craving (and to find that that too disappears). And the best thing is that there are loads of people on here who will help you, give you advice, encourage you.
