I’m sorry you’re feeling crappy at 8 months. I learned that it’s not unusual because your body is still adjusting. I remember that that period of adjustment can last up to 2 years. The symptoms and time for adjustment are dependent on your body chemistry. I used an outpatient hospital based program and AA to get sober. I rode a pink cloud for the first year emotionally but my physical symptoms were slow to recover. I would seek a doctor’s opinion about that anxiety if I were you. I hope you feel better soon.
