If you drank one bottle of wine per night, everyday for a couple of years, this might mean your body is an alcoholic, even if your mind isn't.
Weight loss WHILE drinking... or weight gain after quitting isn't unheard of. Your body will take time to start absorbing nutrients again and to burn non-alcoholic calories - - >burning fat.It sounds like you had a strict alcohol routine.
Your body can take up to 2 years just to regulate REM sleep patterns after sobriety. Imagine what the rest of your body is doing to try to adjust. It might seem long to you, but not to your body. It has to relearn basic metabolic processes. We all like a craft beer or too much red wine. But it's still a toxin to every organ in your body.
Be patient, flush more water, minerals, and greens into your diet... and cut *other simple sugars* that mimic alcohol in your body. Sodas, flavored coffees, white pastas, etc.
Quitting alcohol is really hard. You have done something huge for your heart and liver. Your brain and sleep. Don't push too hard, too fast.
I did that and got really buff. For like a year. Then when I injured myself... I rapidly gained the weight back as well as the habits. Because I didn't really change my habits. I just worked out more to burn those calories. That is the worst thing to do, but I thought I could do it bc I'd *previously* been thin my whole life.
But my body now is apparently different. So don't go fast. Use an online BMR calculator (calories you need to stay your current weight) - then deduct only 20% of your calories. Eat THAT amount by measuring on a digital scale. It's literally "3 oreos less per day". If you stick to that, your weight loss will be slow. But you can mostly maintain a normal lifestyle and still lose bits of weight. I'd recommend that method considering your previous alcohol consumption (been there!) and your current not losing/not gaining pattern.
Shave 250 Calories off your day. That's it. Stick to it. Increase after 6 months to 25% - see weight melt slower, but more safely and with less muscle loss. Celebrate each milestone. Quitting drinking - Eating Better - Losing 10 lbs - Quitting a Snack... those are all small, but meaningful changes that can last if you realize that faster isn't better.
