Hi Penny55,
Welcome to the site! Glad you're here. The first few days, or week, is always a challenge because we go through so many emotional upheavals, self-loathing being one of them. It will pass, I can assure you. Be patient and thoughtful, however, loathing doesn't help. You are where you are, the important thing is to move forward in a positive manner. I know, easier said than done. You just have to ride it out. Drink lots of water and start getting your vitamin stores back in place. Have a read through this to get a better idea:

Another thing that helps is to boil water and put a good slice of fresh lemon in it. It will help to cleanse your liver. Expect your sleep habits will likely be disrupted over the next week or so. I takes a bit of time to detox, however, it is well worth it. Your head will clear and you'll start to feel healthy again.
How much have you been drinking? What is your goal? Quit completely, moderate? We're all here to help and you'll get a lot of support so keep posting, share your thoughts and use the tools on the site and the diary to track your progress. Life is so much better without the baggage of drinking too much. Good for you for reaching out for support. Well done!
All the best,
