Your sobriety is first and foremost the most important health decision you can make, so youre on the right path, both physically and mentally.
While I am not a doctor, I will share with you what my doctor said to me : The human body is a miracle within a miracle, and while we can stress out about a million things that can go wrong, our body was designed to survive very harsh environments, and as a result is incredibly resilient and self healing.
In other words, if you give your body a chance, it will do what is necessary to heal. You're doing that, congrats on 9 months.
