With me, it seemed to appear all at once. My struggle with it was when I had liver cancer and my liver was really compromised. After cancer treatment and surgery, plus the help of diuretics, everything went back to normal. If your hubby has not had any ascites or edema to this point, it's unlikely he will have any unless he drinks again...then there's the possibility.
Emma, there's a difference between being aware and worrying yourself to death. Please try to relax. As long as he stays sober, his liver function will continue to improve...unlike those of us with hep C whose liver is being attacked 24/7.
Hugs,
Connie
