The liver tests came back great! I'll get the results in the mail in a few days, but the doctor's office called me to tell me that one of the things they measure was back in the normal range and the other was only three points above normal. The one that is still above normal had dropped from 147 to 58 if I remember correctly (55 or lower was normal), so it's a huge improvement. The doctor seemed very surprised that there was that much change in such a short period of time.
I have no idea how much these things helped, but I took a multivitamin once daily and 300mg Milk Thistle extract twice daily. Also drank a lot more water than normal and ate really well (lots of vegetables and fresh fruits, whole grains, lean meats.)
I think I'm going to give myself at least one more full month of healing before I start that 3 month antibiotic. I'm feeling really good about my sobriety right now though.
