Welcome, edyta. Congratulations on day 8. I am glad you are here. SR is a great place for advice, support and information. Your drinking consumption sounds a lot like mine--I was drinking that amount in a 5 year period, 6-8 pints of high abv lager a day, sometimes more, rarely less, and had severe hallucinations and complications--it truly is a poison--I do not miss that hideous, all-encompassing anxiety on awakening, either.
I had horrible rosacea when I was drinking that went away after a couple months of sobriety. I got extra bloated at first but that went away. People started to comment about the light in my eyes, my color came back and I just felt better and could hold my head high. I had neuropathy in my hands and feet that took about six months to heal, and is fine now.
I was overweight but through cycling and yoga and healthy eating I've lost sixty pounds in two years. I have been sober since December 2015 and things aren't perfect but they're good, and that's enough.
I wish you all the best on your sober journey.
