Before I quit drinking I had been experiencing a pain in my RHS across my ribs, it felt musculoskeletal to me. I went to the GP and she told me that they were going to test bloods and ultra-sound my liver. I was diagnosed with fatty liver and told to stop drinking for 12 weeks and go to see a consultant. I went to the consultant appointment and the first thing they do is weigh you. They weighed me and I had lost 10kg (I had decided just to quit at the fatty liver stage). The guy was genuinely surprised. I also told him I had decided to quit and I have never been called back. My liver is fine.
Weight loss will come fast if you quit alcohol and through your sobriety, eat well, sleep well and look after yourself better. All of this will result in weight loss from where you currently are. I hope you keep going and prosper. Don't despair too much, you are not alone.
